CRYPTOCURRENCY | Java Web Application for viewing Cryptocurrency prices | Cryptocurrency library

I try to scrape a website using Selenium. I got a problem when I try to get the coins name. because there're 2 elements inside 'td' How can I get rid of another element I don't want. or keep track to only its first element. (I found this post but I'm not sure if it answer my issue or not)

This is my whole code

As my title said. To avoid deprecated warning of Selenium.I try to use the new format as I found. and somehow result return only 1 element. How can I fix it to return elements? FYI I scraping website. I'm working on Colab so I can share with my workmates easier.

Here my code

I am having an issue related to validating cryptocurrency wallet addresses, specifically USDT.

USDT can be validated either as a BTC or ETH address, depending on the network type.

Basically it goes like that:

• If cryptocurrency is USDT and chain type is ERC20, validate the address against ETH address format.
• If cryptocurrency is USDT and wallet type is OMNI, validate the address against BTC address format.

I haven't managed to find a specific validation for USDT:TRC20 addresses and I am not sure how to validate them.

I am developing a regression model to predict cryptocurrency prices, and I have created a simple loss function. The idea is simple the Y target is the price change from a certain lookup window, so either the values are positive or negative. The idea is to first apply an mae loss function and then penalize where y_pred is positive and y_true is negative and vice versa. And reduce the loss where y_pred is positive and y_true is also positive and vice versa. Yet when I train with my loss function the precision does not get higher then 0.50 where it gets to around 0.535 with the regular mae loss function. Any idea what could cause this?

The loss function:

I am running a Cryptocurrency-trading python program on my laptop It monitors the market every second and when the condition is satisfied, it tries transactions.

When I run it on windows CMD, it causes many problems below.

1. Sometimes, it halts till I click the cmd window and press 'enter' key

2. Sometimes, it causes many unknown errors.

However, when I run that on VScode, it does not cause any problem.

I wonder what makes the difference between those two environments.

I'm trying to embed this CoinMarketCap Price Marquee Ticker Widget into my NEXTjs app and am having issues with this. I'll go through what I'm trying to do and walk through my process. Hopefully someone has maybe tried to do this and might have some suggestions.

Here is the code that is presented on the CoinMarketCap website, ideally for an HTML page: https://coinmarketcap.com/widget/price-marquee/

I have two datasets that I am trying to plot over each other.

The first dataset is the daily price of Dogecoin. I am using yfinance and mplfinance to chart this.

The second dataset is a CSV file of Dogecoin wallet transactions, which has a column named "Balance", that shows the Balance of the Dogecoin Wallet at the time of the transaction. The balance fluctuates as cryptocurrency comes in/out. Below is the CSV for reference.

I am trying have the Balance as a line chart, to show the fluctuations in balance.

Below is my code. What I am trying to accomplish with this code is to chart the Dogecoin Price, then chart the Balance from the CSV as a line chart, and have the charts overlayed with each other. When displayed on the chart, I am trying to have the dates from both datasets be the same, so the data is properly displayed.

The first problem is I have been unable to figure out how to plot these two charts over each other. The first chart comes from mplfinance and the second chart comes from matplotlib. If these two modules cannot plot over each other, then I can use a csv of the Daily dogecoin price instead of mplfinance and yfinance.

The second problem I have ran into is my Balance plot does not fluctuate when the balance decreases, it only increases.

I'm a total beginner with Python/Django and trying to understand why this isn't working. I have a function that contains a for loop, doing some logic and then updating a model. but when I have more than 1 item in the loop I get a UNIQUE constraint failed: app_token.token_name error.

So I think I'm misunderstanding how the loop is working?

Creating a scatter plot with vega points are only plotted up to the 11/12th of every month? I'm confused as I feel like everything should be working fine, however this clearly doesnt seem to be the case. Is this due to the data? or the choice of graph maybe? Feel as though there should be a solution but going through the documentation i can't find one
