It sounds clearly that you want make 150%+ profit per month but I don't think that is possible with legit investment Because legit investment can't give you such a huge profits in month , But still here you can make better investment in the altcoins and probably you will needed to invest in better coins and also the coin Should get net increase in the price , otherwise you will needed to wait until the price get . So just trade with that amount of the bitcoin or money that you have in perfect way .
And here I would like to suggest you that don't get into panic and Don't sell your coin until it get a better price because to sell at low price is not a better option to make profit or even to remain away from zero profit and loss , so you should have patience.
