But what is your reason for buying and holding these coins? What type of profits (fiat/btc/eth/other) are you hoping to achieve and have you already taken profits?
Do you genuinely believe any of your altcoins can genuinely surpass Bitcoin or Ethereum's market values in near future?
Buying and holding it means that the coin is indeed a lot of interest, but to hold it means we see the potential of the project is very worth holding on to because it will generate far more profit than what is invested normally will hold it in the long term.
I don't believe that it will happen in the near future, the proof is that currently bitcoin is still no. 1 and is still the price mecca for all coins, but in the long run it may happen as technology advances will create amazing coins.
