I would suggest you wait until you know the answer for yourself, to convert your fiat money into btc.

To me, your question suggests you do not understand bitcoin yet.
From which I further deduce and assume that you probably wouldn't know how to safe guard them against loss.


I suggest you read this;

Note the date it was written.

Read that and you won't need to ask whether bitcoin will be "myspace".



And for when you finally have the answer for yourself....

Welcome to the fold & HODL!!!
