l don't think the same about every altcoin, that is why the performance of every coin is so different. For me, top altcoins ETH, BNB, etc are the best for long-term investing. XRP can be also a good choice for the long term, but as l mentioned top altcoins are not a good choice for short-term investing. On the other hand, if you can be enough patient, you can earn from ETH by long-term investing.
Bitcoin is already 20% higher than it's previous ATH: $20,000 -> $24,000
Ethereum is 2 times lower than its ATH in USD and more than 4 times lower than its BTC ATH. Bcash used to cost a whopping $12,000 at one moment, now it costs $300. XRP went from $3 to $0.6
And these are top coins, so I'm not even going to start recounting how many coins went to zero in the last few years.
It's pretty clear that holding any altcoin for years will lose your money, either by losing compared to BTC, or by straight up losing USD value.
but i believe top altcoins such as ethereum is a good coins to hold mate
as we see now, ethereum already break its ATH, and i'm sure other top altcoins will follow to except xrp
the new season will boost the ETH price and the retouch can happen around $2k price. It is so obvious that the new alt season will boost the all dead and alive altcoin if the ETH can cross the $2k price tag. The XRP case is a bit complex and different, maybe the solution between Sec and XRP will be the new "excuse" for the boosted XRP price. Anyway, it is worth investing in reliable and solid projects nowadays.
