Yeah, Elon's tweet might have put some more stress onto Crypto. But look at the Graph.
The whole market is stressed right now and plummeting. Some might say it's still due to Elon, but if one meme-man can bring down whole economies I'm done. (This is FYI not the case)
This is to be expected. The cryptomarket is not completly untethered from the stock market. Especially not since there are so many institutional players coming into Crypto in the recent months. This is fine, this is healthy. Buy the dip, don't worry too much about Elon and other people tweeting. Chillax, go to Winchesters, have a pint and wait for the whole thing to blow over.
