10x, it seems very difficult to make a profit in doing the current trade, therefore if you want 10x profit from the capital you have then you should choose a coin that is low in price.
Even picking a low price altcoin its not 100% guaranty you will earn a 10x profit becuase there will be a chance this altcoin will go down lower. By the way those project that OP mentioned is sound new to me if I have a $50k I will split it to 50% btc 25% eth , 15% eos and 10% iost since we already in bull run situation I'm sure you will get a good ROI.
