Since you are looking for such realistic profits then you do not really have to take any crazy risk to obtain those profits, you could invest in bitcoin which is the best coin in the market and there is a decent chance it will go up during the next year, but if you want to invest in an altcoin then probably your best choice is ethereum, ethereum has a high possibility to give those profits and the risk it will disappear or crash too hard are very low so it is the perfect investment for someone like you.
