this is cryptocurrency market and you are in the altcoin part of it. 30% is what you earn in 1 day or worst case scenario in 1 week. not in 1 year!

look at some of the charts to see how price has been moving for each of these coins that you have "invested" in. and stop trying to hold altcoins, start learning how to trade instead. you buy these coins in the dips when they are low and dump them as soon as they reached their top and take your 30% and invest it in the next altcoin. rinse and repeat. in 1 year you would have a lot more profit and a lot less losses this way.

p.s. the only thing worth holding for long term is bitcoin because it has real world usage and that is growing. the rest are pure speculation tools.
