I began exchanging altcoins with an ammount of 0.07 eth. I got it when I sold my ACC token. When I have gained my eth, I got some Token that I trust it will soon rise its esteem. I have gotten it 0.03 eth and sold it for an ammount of 0.07 eth. I think there is no perfect number aside from having ammount more noteworthy than the installment for the GAS including store and pull back, what's more you ought to have enough eth to purchase different coins. in the event that I am to recommend you ought to have 0.1 eth or more prominent to completely expand the capacity of purchasing tokens then solding it at a beneficial ammount.
