there are already solutions for the conversion worked on. Conversion between currencies will not be a problem. Everything can be denominated in btc without the need to be actually btc. Don't know what's so hard to understand about it.
It doesn't make sense to bloat to 1 terrabyte in a year and force every user to download all these microtransactions when using another chain is the most rational thing. Man, i'm getting tired. I'm out for now.
Are these currencies pegged to Bitcoin? If not, when why should I choose not to use Bitcoin?
not 'pegged' ... 'pegged' isn't possible. 'peg' doesn't even exist. Crypto is freely convertible actually or just virtual (convert without converting) ... but that's likely too deep now since you are still stuck with the idea of an impossible 'peg'.
You can use bitcoin wiithout using the btc chain - it's totally possible with altchains and those tokens are convertible - actually or virtually. Too much now. Need to go. You figure it out...
sidechains = pipedreams, doesn't exist
most these pro-fork people are dancers in the sky with no grip on reality.
