There are better places to put money, in my opinion. But if it is wrong, it depends on your point of view, and it seems that there are very different opinions about it here.
If you want to gamble, the best way is to learn some basic investing and put your money on certain altcoins, hold enough and know when you buy and when to sell, so you can have more reasonable expectations of whats going to happen. Pure gambling is just too much luck involved. Sure, investing requires luck, but less so than gambling.
