there is always a reason why an altcoin is super cheap. and there is even worse reasons why an altcoin is below 1 satoshi. it is usually due to them being absolutely useless and without a BTC market. they are being traded against small priced altcoins such as Doge and don't have high volumes. any investment needs to be smaller compared to bigger altcoins and also they have a ridiculously higher risk specially when you say you want to "hold them for a year"!
