Disagree too. Some youtubers are like this, but like me (i think), i try to give back when people use my code (and u can tell too that we can have between 2.5 and 6% for the big ones....). Last live session, i used 16 differents codes from subscribers, cause i want to share the money i win with them !
Also, yes, when u start on genesis, u have to take the point about difficulty, cause if u dont, u cant buy contracts here !
For me, even if i have less if difficulty rise, i do all this cause i believe in the future of those ones.
So even, like we saw on Dash, difficulty doubles, i dont care cause i believe that the price will rise soon or later and i ll earn some more profits.
For trading, i saw so much people loosing so much money when they bought thinking they made the good choice, and 3 months later, still no profilt and loosing money.
More, i dont have time to look charts all days, thinking about if go up , down, i mean, i dont have this time to do !
For me, best one now, is BTC, cause i think we cant see it down enough to stop on genesis, so think it's a good one.
U can have too eth, but, long term cause difficulty rised so much.
All are not bad people ! :)
