Investing in cryptocurrencies is risky but there is a big difference between investing in some other coins and investing in Bitcoin. I personally think that those who invest in Bitcoin should take sound and reliable decisions for their investment. Their plans are mature enough. Investors should keep in mind that there are a large number of altcoins in cryptocurrencies, some of the coins in which the investment will never be recovered. People lose their wealth investing in different coins because of greed but I have never seen people who invest in Bitcoin and lose their wealth. Bitcoin is temporarily bearish but can recover if someone is able to hold it.
There are really many such people. If you think that everyone who bought bitcoin made a profit, then you are wrong. There are a lot of people who bought at 40k, 50k, 60k and even higher, but later on they sold in a bear market to save some of their money because fear has kept them from hold their coin to this day.
Just buying and getting rich will not work, you need to be able to choose a good entry point so that later fear does not force you to make rash decisions.
On the other hand, there are those who bought bitcoin at 40k - 60k and still hold it and perhaps continue to buy and average the purchase price, this is also not so simple and only those who really believe in bitcoin will do it. I think such investors have a very good chance of surviving the bear market and making a profit in the new bull market.
