Yes, the information on this thread is so true. To be honest, while a lot of people still don't believe in Bitcoin and still call it a scam, Bitcoin may be the only cryptocurrency I have a very high percentage of trust in. A lot of people's experience with some of these failed cryptocurrencies may even be the reason why they don't believe in cryptocurrencies anymore. Don't get me wrong, you shouldn't, cause of this believe that altcoins are scams too. They're not. They're just not as strong as Bitcoin. Some of these are good, like too good and trustworthy, Ethereum, but not all of them are food enough to be HELD for long.
In finance, people spend, and save/ invest, in cryptocurrency, people trade and hodl. You can very much trade altcoins, but I don't think it's such a wise idea to hodl them. Bitcoin should really be the only crypto you hold for long. You can do you if you feel some altcoins are worth hodling. This, at the end of the day, is just my opinion.
Either Bitcoin or altcoins I don't tend to hold any for long, I will take profit when Bitcoin makes a new all time high and buy back when a massive sell off happens or after a bull market is over, this is how to secure fund and end up with betyer amount of Bitcoin later.
What I won't do is buying the same old altcoins from the last bull market again, this is where there is a massive difference between altcoins and Bitcoin, it is very hard for old altcoins to make a new all time high again, most of them died after their first taste of full bull market.
This is why I always abandon the old projects and focus on the new ones that raised a lot of money, minus the likes of BNB and Ethereum, even if you plan to retire with Bitcoin it makes no sense to hold through a bull market into another bear market, like if BTC reach 90k i will sell all my BTC and maybe buy back in 2026 when a new lows happen.
