How did they say that this is legit? Any proof of trading history? I think that is the main thing that will be asked by a curious or interested person and its your duty to provide it, only real.
Well, he just say what should we do, lets say "buy (coin) on 570 and sell them at 620" i think he mean dont go higher than 620. But for now i just watch the price at coinmarketcap and what he said is almost accurate, of course i cant trust him too much for now because maybe too risk. But I will keep update it depend on the price on coinmarketcap
Why should we follow him? Most of them are doing this service to benefit only themselves. To pump the coins they already have. This is not recommended to traders who only got small capital because fees sucked.
Same with you, I also monitor using coinmarketcap prices. I check it every hour as I can.
Trusting this kind of service is very risky because you don't know where they base it and they don't have any title to consider as official to be trusted.
