Invest some of it, yeah. You have to realize how frigging volatile bitcoin is, though. There's nothing that says we have to stay at or break above $2500. We could be back down to $1500 or lower by tomorrow. Do I think that's going to happen? No, but it's possible. So if you're young and don't have a retirement plan and have extra money to play with, do it. But be ready to lose money...and hope you don't.
I wouldn't put too much into crypto.
I think the value of bitcoins is raging up maybe if you invest past few years ago maybe you're rich now, so sad, or maybe you can invest in some altcoins and maybe it will become a bitcoin or in other word an altcoin that you will rage up the price soon like ethereum. For now bitcoin rapidly increase it's value which you can consider it. Bitcoin is tested and proven to be a good way to invest our money.
