How long do you hold your coins?
Some coins I have a couple of months like Sia.
Some years like Ripple
It depends upon the price. I use my coin to earn income or get profit so i'm after the price. My usual routine is wait for a while and when i think the price is decent, then I'll exchange for it, then earn again and so on. But sometimes i break this routine to give way to urgent expenses and exchange the coin immediately without considering the price
