I invested in ethereum when it was $700 in 2020 and in 2021 when it was $4000 I sold it. I just bought again now that the value has reduced. I still trust that it will increase rapidly soon.
Well you made a profit in 2021 - so props to you for that since many users here did not sell and lost the opportunity, something you should consider as an achievement.
It is not that people dont trust an altcoin, some people dont but that point should be in making profit and getting out in a green streak. Ethereum is not the first go coin for users in a bitcoin forum but there will always be people rooting for the coin that is 2nd to bitcoin.
The coin I trust the most is Bitcoin. But keeping your choice open in the crypto world usually leads to more losses - so I restrict myself to the top 5 altcoins only.
