Unfortunately, first of all, there are not many opportunities to spend bitcoins. And in addition to it, the most of things where bitcoin could be spent are illegal
It's just the stuff that you came across because I used btc to buy some gift cards and rdp accounts which were totally legal and 100% usable.
As for the OP, first of all please move the thread to the suitable section.
Have you bought or secured some Bitcoins with you?
Literally everyone on this forum has bought or is trying to buy some bitcoins.
Have you done some trading with them?
That's difficult and unpredictable.
What all do you think a person can do with the Bitcoins? What do you think could probably be the future market of bitcoins?
These two questions are way too generic.
