Do you know any sites with Bitcoin / altcoin signals?

This has happened many times before with me. It sometimes hurt me a lot in the beginning. It often happened that the prices went up after the tokens were sold, so I was very upset on the situation, But that's when I started working in crypto. But now I understand that this is a market and prices fluctuate in the market.There is nothing wrong if you sell them first and then the price goes up because you took advantage of it religiously.

For the past few month, the Ethereum blockchain network is looking busiest ever to process a tremendous amount of transactions. If you have sent ETH or ERC-20 Tokens with lower Gwei or nonce(Below the standard gas price), maybe you have been waiting for a long time to get your transaction to be confirmed. If you are Metamask wallet user, you should have a chance to speed up or cancel your transactions(Metamask attempts to cancel transaction if it is in pending state.Transaction can still be canceled if it is not included for the block confirmation and it can be done by sending another transaction with the same nonce, but the gas fee should be higher). If you want to speed up transactions, click on the "Speed up" option, and select the standard gas price.  Sometimes a faster transaction does really matter if we are on the way to meet a real-time market momentum to get benefits.
