Why not do both?Sell a part of your bitcoins and HODL the other part.I'm not giving any advice here,but maybe this is something I would do.The profit would be smaller,but if the bitcoin price crashes soon,you will have some fiat money to buy cheap btc.
True! If you aren't sure about what to do then do both, if incase it'll crash then yo still have btc left to bounce back again. It is like testing the waters, meaning just to also test the market if it goes higher then good but if it goes down still good because you still have left as reserve, it is still a win-win situation.
What's been suggested is a secure way of trading. Crypto trading is high risk associated process as the price dumping and pumping takes place in a very short time period. Users who prefer to have a secure profiting can keep hold of it without getting into trading practice of buying at a lower price and selling at an increased price. Quick profiting is possible with experts and with lucky traders.
