i want your opinion about this, because i have lot of coins am holding
Of course yes as long many people believe and many people still using altcoin will long last in many years and I think altcoin is the big help in crypto because of its contribution to grow more the crypto.
I think the opposite. After 5 years, most Altcoins will die and few will survive. Most of them are rubbish and are created only to enrich their owners. I think that they will not survive the next bear market.
