Compared to other platforms, creating a smart contract and token has a lower creation cost. Looking at the blockchains of NEO and BNB, each contract is created and requires a huge amount of money. For BNB it is 50,000BNB and NEO is 100 to 1000 GAS. As such, every ICO project hosted on these blockchains is more serious. But according to market rules, if a project does not have a large enough leadership and investor and strong partners, that project will soon fail. Almost all projects organizing ICOs, IEOs and STOs have greatly reduced their token value.
so all of these scam ttoken project-based atempts are ethereum fault?
as erc-20 are belong to ethereum platform and many abusing it due how easily creating tokens without any strict requirements , other platform as you mentioned above have more strict requirement which it is part of an effort to fight these scam attempts.
actually you can minimize the risk get scammed by those fake projects by looking at how long the project has been exist , if it was running for years then that is a promising serious project , mostly the ICO itself is a new project that not exist before , this add more risk to you.
even though not all the new project are bad , choosing a project that has been exist before and tokenize their project is the prefer one for me, obviously they are serious real project since begining before even the token era.
