IMO this fall is fine for blockchain tech. If bitcoin "dies" this fall, regulators will not feel as threatened by it, and we will see less russia style bans until bitshares or another altcoin has attained critical mass to rocket cryptocurrencies back into the spotlight. bitUSD, not bitcoin or some other coin, is what will seriously threaten the monetary sovereignty of countries like Argentina, Russia, China, Vietnam, etc.
Bitcoin has been great for creating a solid cryptocurrency infrastructure. If it continued to be successful for another couple of years, it would still not gain long term success due to PoW mining, but it might give the authorities a test battleground where they can learn how to fight cryptocurrencies. IMO it is better to have the facebook of crypto ready before we begin the global war for monetary sovereignty, rather than sending in myspace first.
