It's not so difficult to see gem coins or ordinary altcoins, generally people say the first coins because the selling price is very high, altcoins actually have a slightly cheaper selling value compared to gem coins.

While gem coins have a high selling value, that's why they are called gem coins, for example bitcoin, ethereum, BNB and others, in these circumstances our opportunity to invest in gem coins is very small, there is almost no opportunity.

Or what do people mean by gem coins like meme coins at that time, initially meme coins were not taken into account, even the purchase price was quite cheap, but at certain times the meme coins rose significantly enough, so people considered meme coins as gems.
