You're statement is more of a generalized one rather than specific, which drives it seriously our of context. Bitcoin evangelism is very good and what I root for, but being a button maximalist is very bad. There are surely other promising digital assets rather than Bitcoin, there's Solana which I wear the signature of a company endorsing it, there's Ethereum, there's BNB which provides us recently with a network to transfer  USDT free and much more. These are good and promising projects although they're not in any way compared to Bitcoin in value, but it's noteworthy that each serves it's purpose in it's own capacity and has not been linked to pumping and dumping, thereby defrauding people which is the real meaning of scam in the context

This is a bit of unverified proclamation that you've made here and I'll not support it at all since there's no evidence to support that every other altcoins are scam. I also advise you to refrain from such maximalist and unverified statements, so you don't bring lawsuits or issues for yourself on the long run.
