How long have you been hodling a particular coin while the coin has been making progress for your profit taking and yet dropping in your eyes ?
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

Bitcoin is good for longterm holdings but new altcoin is not a good choice. There are coins that you find it easy to earn but after a month the coin is not that good for investment because it totally goes down.
