One problem can't solve from first, if new investor can't trust new fresh coin why they don't invest in old coin. We several good coin already exists in cryptocurrency even with very low price. Even I don't think there could be a trust problem. All solution is now is the correction time!!
Corrections will definitely happen and in my opinion this year will be a turning point for altcoin to rise in price. For new tokens or coins, it takes time for investors to believe and investors will definitely monitor product developments. In my opinion, now investors have started investing in old coins because of low prices on the market
