I was away from crypto for years and now I'm trying to get back into the game. I was really STUNNED that there is no exchange, even after many years since bitcoin started, that we can just deposit USD and start exchanging altcoins. I hope I'm wrong because this would be the single biggest hurdle for altcoins to be widely adopted by general public. There are just too many hurdles to jump over just to START trading.
Well, try the minimum one, try to trade which you won't regret if you lose it. It is hard to dive on bigger if you aren't familiar enough on some stuffs you will dig. Especially, money is involve and once you dig to it, it is very tough to get out it is matter of winning and losing. In addition, try to ask somethings you didn't understand try to familiarize some circumstances , and the possibile result that could happen. Well, that is all.
