Yes I spend my bitcoins a lot on the online bitcoin market, because there is more to buy these days.
I also gamble a lot but this is with low amounts only so I will not lose a lot at the end.
I only invest now in Bitcoins. Because I think it will be more worth later.
But I take the risk that I can lose money too, but I hope for not.
That is the risk that we all take. The price could drop a lot in the short term. But it will rise eventually.
