For investment purposes, I wouldn't invest in a stablecoin. It's more or less the equivalent of parking your money in a savings account and making 1-2% on your money. I generally use stablecoins when I sell my crypto and Bitcoin. I transfer them to a couple of different stablecoins and then just wait for a pull back/crash on crypto like what has happened this year and then slowly buy back in.
I haven't heard too much about the algorithm being cracked by a supercomputer, so don't know too much about that. I will say that usually when Bitcoin crashes, there's a LOT of scaremongering that always follows. The truth of it is, they the big corporations don't want people buying when it's low like this. And then when it moon shots, the articles are the complete opposite trying to get the public to buy. I've watched this play out so many times. They use all the social media platforms, so I always advise anyone to do the opposite. Hell there's even rumors that Epstein is "Satoshi" the inventor of Bitcoin. I find that laughable tbh.
This is the 4th cycle I've seen happen like this. I've been investing in crypto for 12 years now. When it corrects like it is doing now, buy! And then keep buying smaller amounts every month with what you can afford for the next 3-4 years. That's always been my strategy. If you read this thread from start to finish, you'll see how the pattern plays out.
