But why BTC is the only coin people feel like hodling more than 6 or 7 years? Is it becos d coin was d first coin in cryptocurrency or base on d results other investors have achieved from it, becos d confident we have in hodling BTC for long is different from other coins in d community.
Bitcoin do and do increase to all-time-high as usual, but some altcoins failed to do that. During bull market, altcoins may not reach all-time-high again or in time. Some coins are shitcoins and some become dead.
Let me give you some good examples:
Bitcoin increased to $69000 in 2021. Now at $29300
Dash increased to 478 in 2021. Now at $31.80
Filecoin increased to $430 in 2020. Now at $4.2
Solana increased to $259.9 in 2021. Now at 23.17
Most altcoins are still 10 times lower than their all-time-high in 2020/2021, but bitcoin is just not more than 2.5 times lower.
In 2020, bitcoin got to all-time-high above $19600 of 2017. Its price increased to $69000 in 2021 which is the present all-time-high. There are many well known altcoins that did not get to all-time-high at all in 2020/2021.
Examples of coins that did not get to all-time-high in 2020/2021:
EOS
Bitcoin cash
Zcash
And many other coins.
Like I have once mentioned, your topic is about bitcoin and this can be taken as an investment assets, but altcoins are gambling assets and only use them to gamble.
After a significant bear market and if you are able to risk your money, risking the amount of money that you can afford to lose, there are some altcoins to go for, but not for long term investment except ether, but which I will not encourage anyone to invest on due to privacy reasons and centralization. There has been no coin like bitcoin.
I can only advice people to invest in bitcoin which is less volatile, most decentralized and most secure.
