You are saying a lot better. All Altcoins are used only for promotion. There are those project owners here. They always launched the project considering the profit. However, not all Altcoin.
I think that not a few of the altcoin projects used are focused only for promotional purposes, usually these tokens are prone to market manipulation, not a few projects that last only temporarily because the main goal is not to focus on utility but on how much profit can be obtained.
If you are an experienced person. Then select Altcoin through analysis and invest. Yes it is exactly what we have to keep focus on Bitcoin all the time. Because about 50% of the total assist should be kept. That's exactly what I do but 70%. In the case of Altcoin, I use the top currency so that there is no harassment and there is no possibility of losing money.
First of all, it is very important to diversify assets, if you want to invest in altcoins, you can invest in top coins, maybe you can see references from CMC, many of which have great potential in the future, such as Solana, Ethereum, Arbitrum, etc.
