Some are promoting SmartBCH and they say to convert our BCH to SmartBCH. But that's created on Ethereum ! Is that correct ? I never understand those who convert their crypto to other wipped one, or how they usually call them. How could be the copy better than the original ? Isn't better to just hold the original token, on the original blockchain and the official wallet ? Instead of supporting Ethereum, another blockchain ? I'm new to all this swap thing, but I hear about it a lot. Maybe someone can explain to me that in simple language ?
It is a sidechain to Bitcoin Cash, but has EVM (Ethereum Virtual Machine) compatibility. It is not build on on top of Ethereum but compatible with Web3 apps and websites. As a blockchain we can say it is a clone of Ethereum but I think this is very generalized description. It uses BCH as Ethereum is using ETH for gas.
So, smartBCH is an independent blockchain? If so, where I can check the explorer and is it listed on exchanges ? And do you advise to invest in it, or it's better to hold BCH ?
It is independent yes, it has its own blocks. Although it doesn't have a native token, as others, it uses only Bitcoin Cash (in a tokenized version). I have a guide that may help you: https://read.cash/@Pantera/smartbch-metamask-tutorial-connect-to-network-transfer-bch-add-tokens-and-trade-on-dexs-601f4b17 There are three DEXs right now offering DeFi. You buy their token, (hoping they won't exit-scam though) and invest in liquidity and staking. Until recently I didn't use them, but I used one today and staked 0.25BCH just to test it. There is risk involved too, so you need to do research. If you are new in Defi (as me) it takes some time to understand everything. My approach is like trial and error right now, hoping it will not cost me too much. But to tell you the truth, it is exciting. There is potential for good rewards.

Or can we consider that a fork of BCH ? Or it's created by the team.
It's not a fork, independent chain running on top of Bitcoin Cash. I didn't read about the mining, but it is not the same as with BCH mining with ASICs and all. I'm not entirely sure about that and will probably misinform you. For this question you should probably ask at the telegram of SmartBCH, here: https://t.me/smartbch_community There are developers of Bitcoin Cash and SmartBCH at this channel and will reply correctly.
