Like everybody in crypto, I spend time to make a profit and I don't think it is a waste of time. Yes there is a risk and we may lose all our saving but we may gain good money as well. That's why I spend time in bitcoin.
This risk will never lose your money rather it will give you beneficial profit and other way it will gain your knowledge and you will better know about crypto world and that's why you will avoid those activities who waste your time and your life may go to in a wrong way, so that's why spend your time in bitcoin currency and get a lot of knowledge about this currency and maybe that is why you will become a richest man in the world by its high price.
