Right now? Crypto. Crypto is booming bro like literally booming so bad.
Spoken like someone who got in at a good price--and that's what it's all about, getting in at the right price. I don't know if crypto is booming or not, because it seems like the market is going sideways right now. But if you'd bought bitcoin in 2015 and kept it, any point in 2019 would look very good. But if you're new and bought at $10k-20k, you're probably feeling a little sick right now.
Bitcoin - in March 2010 - $0.003, now - $6840.
Can't argue with that, but it's a little bit misleading. All of the huge gains may already have been made since bitcoin was at or near zero. Or maybe not--I don't have my crystal ball handy, and it doesn't work anyway.
And I can't compare crypto to the stock market anyway. They're two very different types of investments and the markets act very differently. I like both for very different reasons, and I'd be hard pressed to pick which one I like more. I do think the stock market is pretty overvalued right now, so it's probably due for a big correction.
