That's correct. But lower price coins have better chances to give you profit that higher ones.
For example If you invest while bitcoin is at $6K, you may expect upto a $12K rise but when you invest in coins at price 2 cents, they can bull upto $2 easily.
Technically yes, don't just look for the price of every coin instead go understand its technology and know if its really good for long term. Well, EOS still on higher value right now but since it is being hype right now maybe we will see people to come in without making any research, I'm looking for this technology before but after making time to review this coin well its really disappointing, ETH is still better.
