Michael Saylor, a big name in cryptocurrency, thinks the U.S. Securities and Exchange Commission (SEC) might start cracking down on altcoins soon. This could mean stricter rules for how these coins are traded, which might make it harder for people to buy and sell them. If this happens, it could shake up the whole crypto world, making it less exciting but maybe more stable. So, keep an eye on what the SEC says, watch how altcoin prices react, and listen to experts for advice on what to do next.
