you will never know !!!

old coins is be good to choose ? not really, You dont know behind the scenes..
investors lost the trust because assets is lose 90% - 100% and abandoned by the dev..
if behind the scenes are still active, it's still difficult to recover "btc/alts" maybe it takes a long time
2 years ago price btc a just 500-1,5k$ but now the price over 8k and never fall back. so small whales can't help much in pumping

choose what you believe but don't choose coins that are not supported by miners it's just pure manipulation coins
circle crypto (miners is suppy - investors - markets - players )
