In investing you must research in detail each coin you want to invest and also remember to be prepared to accept any risk that you have decided. instead of investing using cold money. yes, one week ago the market was bearish where the price of btc and also other altcoins decreased in price. and at that time i thought to add some top coin investments of my choice and till today the coins i bought have made quite a lot of profit.
By cold money do you mean savings? I would be not hesitant to invest my savings into Bitcoin but I will wait for the price to rob a little bit more before I buy some more and I have already purchased some when the price was around $28k. So obviously after grabbing the possible bottom prices, like most people I am also expecting the market to recover toward a new ATH.
buy a coin that you think is good and has the potential to be at the forefront of the market recovery this time, and remember, always use idle money capital, and divide it into several altcoins in investing
And even when you invest in a coin that has a good market cap, make sure to follow the news around it. Ripple has always been among top coins but people who know problems they have with SEC will hardly ever invest much in it.
