Mining in 20 years time

[Clement Kaliyar]

Bitcoin 1.0 may die 2017-2018... Bitcoin 2.0 go in September 2016 - https://bitcointalk.org/index.php?topic=1616884.0   http://www.bitcointwo.xyz  ... Maybe in 2020 will be Bitcoin 3.0 ...

what kind of projects are those!!!!! i am hearing about those for the first time looks like some copy cats wannabes ,what ever it is in 20 years time the kind of big miners which we see in china right now will be closing their doors as it wont be that profitable unless and until bitcoin prices triples from what it is now ,transaction fees might increase and i expect the core developers will find a solution regarding that too.

I haven't made up my mind yet if increasing the block size is a good idea or not
what I know for sure that mining in 20 years time will have seen us through at least 4 reward halving,
so the block reward is smaller and the miners main profit is from the transaction fees
how will this affect the speed of transactions?
are  bitcoin v2,v3 or any changes to blockchain  really necessary?

Increasing the block size is good if you want more transactions on the main chain so that there will be more users.
