@xianc78 99% of the cryptocurrencies are a scam, mostly because there's almost always either a corporation, or a personality, or a government, or some other centralized dev team behind it.
Then there's bullshit like dev taxes, ridiculously high transaction fees, network being centralized (because they're just too much of a hassle to set up and/or requires ASIC), smart contracts, or something else.

That's why Monero is perhaps the only crypto that's not a scam.
Maybe Haven could potentially be good too, but I haven't looked into it too much yet.
