I don’t think any of them have a real future as a means of payment in mainstream finance. I do think that you can make quick money on them & get out ASAP into safer, more reliable investments though & that’s the aim for most meme coin investors.
Do your own research but there are opportunities out there to do very well in these projects. Just don’t hold them long term.
DOGE might have because it's the most famous meme coin, and it has been accepted in most if not all of the centralized exchanges out there.
I feel regret that I invested into SAFEMOON back when meme coins are a hype. If only I just invested into DOGE at that time... but shit happens I guess, and I know that there are some here who also lost in investing into meme coins. TBH, if I will look at the best meme coins that's worthy of investing, I only see DOGE, but even that coin isn't a good long term hold for me, but it's a good short to mid term hold I guess.
All of the other meme coins are considered shitcoins for me - including SHIB.
Like you said, always do your own research, and you will see that there are better coins worthy of investing your money than these meme coins. For the OP, we know that this is another form of advertising your exchange, and there's no problem with it. Can I ask if you can share how many users are using your exchange on a monthly basis?
