There is no room for trial and error because money is involved. That is why we look for suggestions, to avoid more loses.


I would go with ETH. Like bitcoin, it deserves its fame and worth. Eventhough there are some technical differences between the two, it wont let you down in purpose and capability.
I think ETH is good for trading.

NOTE: try to do your own research to avoid everyone who suggested altcoins here to be liable for your loss.
Knowledge will guide you.
