If you want an honest trading advice then believe only the ones that say everything is overbought right now. Stay away from altcoins until they have fully corrected. If you buy in now, it will probably result in paper losses, and it can be very frustrating looking at those in your portfolio.
Altcoin can be not like bitcoin as you expecting from altcoins. Altcoins are alternative of bitcoins but not that much power to break the record of bitcoins. So kindly try to go for bitcoin. If there is a bad days of bitcoin try to buy bitcoin and wait for the right time. It just a money circulation that how people are coming and going once again same process like federal bank.
