I advice you to make a bitcoin wallet by that site https://www.coinbase.com because by coinbase you can buy and sell your bitcoin

In my experience the best wallet safe and good is coinbase wallet i have now five years in that site without any problems and without any losing of my bitcoins by hackers

The bitcoin mining is difficult and he have a high risk to lose your money because the profit from it is linked with the price of bitcoin and i have a mining experience in past by genesis-mining.com and i lost my bitcoin in it before the contract end because bitcoin price is increase in that time and genesis mining send me an mail to told me they had take a pourcentage of my profit to pay their bill of electricity and that not  for me only but for all member and after that i send me nothing in my wallet and after that bad experience i don't invest my bitcoin in any mining site

Not all the bounty pay by ETH because they exist many bounty who pay by BTC and you are right about the tokens who not listed on exchange you can't sell them or do anything by it also they exist many tokens earned by bounty and listed on exchange but without value in market so you can't sell them

I think the best way to resolve that problem is contact your manager and i think the manager can give you the solution of your problem

For me etherdelta is the worst exchange site because  many tokens when i choose to sell  it by that site have low price than the real price of these tokens

I don't think now with the high price of bitcoin BCH can't surpass BTC in payment functionality

Before you sell your tokens you must verify if that token can be sell it or not you can sell your token by https://forkdelta.github.io/
