Are you able to hold your coin for years or do you just want to hold for less than one year?
No matter how long you hold a coin, we still have to choose a coin that is really good. Do not just choose shitcoin which will bring us to a loss.
Choose coins that already have big names!
The coin which has great potential to be one of the best will give you profit later or sooner. Cause of that l agree with your opinion, it doesn't matter how long do you hold this coin, it matters which coin do you hold. For that reason l prefer mostly investing in top altcoins, in my mind, they are more profitable for long term investing.
