Is is even smart to invest in bitcoin

Investments are all risky! Bitcoin last year was worth approximately 2k each and then it went up to 19k and now it's back down to 6k. If you had invested when it was at 2k and gotten out at 19k then it was a good investment. If you invested while at 19k and got out at 2k then it was a bad investment.

Investments are all good and bad, the thing is, if you want a shot at getting rich, you gotta be in it to win it.
