If you don't have faith in bitcoins I would suggest investing in a short-term period, But if you have faith you could do long-term investment. You need a large amount of capital to risk and I will also consume your time and efforts. I always remember the GOLDEN RULE "Don't invest in what you can afford to lose" I decided to do a short investment. I can't afford to lose a lot of money. I just want to earn enough to survive
