How can you short it and be sure that you will be paid if you are right?
You can easily short on KuCoin. Its one of my favorite exchanges right now. I see options to buy 3x short tickers on the main coins, and you can also use the margin feature to do 10x. Plus, they have futures as well which provides 100x.
I think before you think about getting paid your sure fire windfall, you should think about how damaging it will be to enter a short position. Ask any TSLA short over the years how well they did. Most recent casualty was Michael Bury. And don't get me wrong, I think its highly over-valued, but it doesn't mean you should short it.
I do agree that the failing of USDT will cause major problems. Heck, KuCoin mostly runs on USDT, but I notice the most popular pairs also have the USDC equivalent. Hmmm.. maybe I should be using those instead of the USDT versions and holding USDT.
But I will tell you one of the things that made me go 180 on crypto. Too many politicians are now involved with it as well (saw this in a CTO Larsson video). No way in hell they are going to crash their own party. Sure, some tokens will get labelled as a currency or security which will impose restrictions, etc, but as a whole, the market is moving forward.
The other way I look at it now is from an asymmetrical risk perspective. BTC will I'm sure do a 10x over the next decade, and perhaps much sooner. Some of the other chains will do even more. Can you really afford to miss out on putting even just 10% of your net worth in this asset class? The dollar losing purchasing power follows an incredibly stable downtrend, so cash is clearly out the window. Bonds earning several percent are also clearly trending down when you account for inflation. I was a precious metals bull but you can't ignore how awful these charts looks in comparison to equities and especially crypto. So what is really left?
