The main thing - do not use only bitcoin. There are a lot of alternative currencies, investing in which, you can get much more than bitcoin. Participate in the bounty, invest in prospective ICO, and then you can "make money."
yes, I also do not just invest in bitcoin, because I think the cost of bitcon transactions is too expensive, I used to use bitcoin if it cost a lot of money, and I also invest in litecoin, ETH.
Why don't you consider investing in some ICO projects? I think the investment ICO project will earn far more than the investment BTC and ETH.
