I saw something on a friend of mine iPhone I was amazed, this guy has 3 pieces of bitcoin but he didn't look it when you look at him with mere eyes, I ask him how he has come this far, he told long ego he was seriously investing on all kinds of coins with little amount of bitcoin but then most of those coins help him to realized enough amount to buy more bitcoin because that was his primary target. He normally buys those zero value coins when they appreciates it will be enough money, and that's how he convert and swag all to bitcoin and today, he has 3 piece. Is good to be diversified in your investment, somedays something good will come out of one you don't expect.
It depends on the strategy and mostly the luck if you have a good strategy but you are not lucky then you still end up loosing,because crypto is really needs a proper understanding with focus it is a high risk kind of investment and not all investors earn on it, sometimes we need to have a limit on investing or even on trading to make a good profit.
