with only 0.1 it is a low number if you want high profits quickly, the bigger you invest the more profits you will get. it is a provision in the game of investment.
Well OP is just new here so 0.1btc is I think reasonable to start up then he can just add some when he already profited.
But of course, he shouldn't expect high profit with just amount but still it will be the safest way here to start the game.
Just do trading with undervalued coin and have patience for it to get pump. It's not a easy road to take but surely will be rewarding.
