first of all useless shitcoins such as ethereum don't have any effects on bitcoin whatsoever. they are only there to fill the pockets of experienced trades that participate in that shitcoin's pump and dumps.
secondly 2.0 is a newbie fooling technique whereas nothing fundamental changed about ethereum. it is still the same useless shitcoin that is only used to create useless scam ICO tokens to dump on newbies and make a ton of money.
otherwise all the bugs, scaling issues, huge fee, network congestion, network failure, lack of immutability, slow synchronization, no security, centralization, huge premine,... still exist.
the only difference that 2.0 makes is that it will eventually give a shitton of profit to those who are holding the 72 million premined ETH.
