Some people don't understand the hodling technique, they are hodling a particular coin and never sell to rebuy again or to sell and buy another coin. You can sell this coin and buy that other coin that is how to turn over your money.
I didn't tell you to sell your bitcoin and not to buy again. I only say you sell the bull and buy the bear
Well, everyone and their own ways, it can also be that they have plans to invest in and hold the coin for a long term, there are people who might plan to hold their coin for like five years or so, because the money they are investing is a money that they won’t really be needing, so instead of keeping it in the bank, they might decide to just invest it and keep holding. It’s never bad though.
