Using bitcoin, I do a lot of things. I use it to purchase items online. It is really convenient since you don't have to reveal your identity at all when buying. I also use it in altcoin trading and investing on some ico's. I only invest on ico which I think will have a good future though, I carefully analyze it, and I gain good returns in it. Finally, I convert it into fiat. I use it to buy my daily needs and that's what I do using bitcoin.
Making a bitcoin trading is very risky, and it seems to me not very profitable, because bitcoin lately longer in a stable position. But of course if you wait a year or two, it just might be possible to make good. But this is a very long time.
