very cheap that we can hold for a year.
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"!
It's true, that there is always a reason but not always due to a coin being absolutely useless. There have been some coins that have been under 1sat this year but went up due to people discovering it, and seeing the technical value behind it.
