I have been reading up on some interest accounts out there for BTC and Altcoins and the yields are really good especially when benchmarked against fdic insured fiat.
What’s your take on this? Is this a good or bad idea?
First, don't mix Bitcoin and altcoins together. They might both be cryptocurrencies, but there's a key difference that Bitcoin is the most reliable project in this field, while altcoins are mostly just investment scams veiled as the next big thing.
Second, Bitcoin already gives you absurdly high returns of investment, so it's simply not worth the risk of losing all your coins to scammers/hackers to get some extra %. Practice shows that when there are centralized custodians that hold Bitcoin, exit scams and hacks are rampant.
