There is too many coins and chains but why need?

.
I would use xlm or xrp but anyone who I deal they use USDT tron.
We have so many blockchains and coins and they don't find use case tron has now number one utilty it's holding number one payment method on tron chain.
Ada dot matic and all the others and ltc....i even can't Understood why we need those ?

I think the use of many chains by Tether was to boost each blockchain network and make it active. You know that USDT is been used every day and because of that, any blockchain network that is faster will have more adoption and will make it more popular and for that reason, the price will adjust or boost more, this is why TRX remain valuable by market cap even though nothing spectacular is going on the chain.

However, have you for once ask yourself why many people still use ethereum for usdt transactions? It's because when it comes to security, there is no any network that comes close, never since Tether has been on ethereum there has been any hack. Sometimes, despite the fees Tether foundation deploy more coins from Tron chain to Ethereum and it even has more coin on ethereum than any other chain despite the fees some people are worried about.

They are many alt-coins as the Blockchain are all difference with a purpose of creation, when it comes for a means of transfer Coin or online payment, considering the cheapest rate, I think considering the following: polygon Matic, Litecoin and TRX Network. The network transaction charge fees is very low to compare Ethereum and other network.

That's because there's a lot of wannabes and innovators that want to make money and make changes to the current system, that's the beauty of competition, you create variety and make it so that we're not susceptible to monopoly and market manipulation, we're also at a much better position with more altcoins because that means that the introduction of cryptocurrency to more people is much higher than that if we only have one cryptocurrency, more people getting into cryptocurrency means that more demand that would make countries/governments consider the fact that cryptocurrency isn't just some sort of a fad and that they need to get their hands on it if they want to get those profits.

There is too many chains and coins.

Just select an established chain or coin like Bitcoin and Ethereum and you will be probably safe.
Most TOP coins are very established already and you can make a good decision by selecting established coins.
Such coins will be much safer to be still leading in a few years.
