Altcoin is not increasing for so many days. New money is not coming in market.So Always invest in good Top 30 Altcoins for being Safe.
I think the new coins also have a big chance, but you have to be smart in choosing those coins. If the top 30 coins, I think the price is controlled. Look at the daily charts, everything is almost the same. I used to think the same as you, it turns out when I learn more, and try to invest in new coins, the profits are far greater than the old coins.
There is no guarantee that the value of those new coin will increase and it will depend on how many trader or investor are trading those coin and also depend on the exchange if its really providing a real time volume.
And some of those coin/token today are just a bunch of useless because only those developers created the project are earning and not the investor.
