Holding generates profit and knowledge suggests various strategies. It is possible to generate profit by buying and holding Bitcoin without knowledge but holding other altcoins and other coins without knowledge will result in reverse loss instead of profit.

So knowledge is definitely important if it is intended to invest somewhere other than Bitcoin.
Investing in bitcoins and holding it for a long term has the potential to earn profits. Investing in bitcoins does not require experience. But when you think of investing in altcoins or other coins, you need knowledge. Because if you make a wrong decision, you will make a mistake. Your chances of losing money will be high. So we have to think before investing. It has to be accepted that by investing in bitcoins you can't get much profit but by investing in altcoins there is a possibility of getting more profit and the risk is a little more to lose money.
