Indeed, it looks very cool. The fact that the coin continues to be added to new exchanges shows an increase in its popularity, as well as an increase in the level of trust in it.
If you talk about Bitcoin and Dogecoin, then it is appropriate to add it to all exchanges because until now Bitcoin and Dogecoin already have a lot of popularity and a very large community and it is only natural that more and more people believe in both coins. even though Dogecoin is still referred to as a meme.
Exactly, top coins have seen ATH levels and chances are slim to hit same price point due to high volume and coin circulation. For higher ROI investing in small marketcap altcoins can be perfect decision but the higher reward means accepting more risks. Small investors should stop listening to Elon Musk and invest in where smart money flows in, IMHO.
