While I don’t think Bitcoin is going to go up forever, you can’t deny the returns that investors have made over the long haul. Even if it is a bubble, that bubble could get a lot bigger.
I got into ETH at $16 since guys at work were into it. I got out around $25 in a couple weeks and thought I was a genius. Then it went to $1,200 within a year or so. Sure it came way back down but is now back up above that level, or at least was last time I checked.
Bottom line, if it’s $1,000 you can afford to lose go for it. I do tend to think it’s too high when everyone is talking about it.
