Which Altcoin is next to Bitcoin and is being accepted worldwide?
For me it is eth. You can convert eth to btc so we can use it. For me ETH and Bitcoin Cash is next to Bitcoin. I also think that it is our job to convert our ETH and Bitcoin Cash or any altcoins that we have before we use it.
I agree with you other than that ethereum also has a stable price, and now ethereum is also good use for short term trading,
