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.
You are one of the lucky person in cryptocurrency. I trust ethereum the most in altcoin. Because ethereum is the king of altcoins and it is the most trusted altcoin. Many new altcoins have arrived, some of which have survived, some have been destroyed. But ethereum still proudly survives. I myself will invest in ethereum for long term.
ETH is also my most trusted. I have a dream one day ETH even flip BTC out of its number one spot for crypto, and become the king of crypto. Who knows, maybe the upcoming crypto crash and ETH PoS over the horizon would haste that dream of mine. Unlikely, I know but we're in the bearish time so everything could possible)
