250K is something I don't agree with. May be one day but I don't think within 10 years. People were actually projecting viewing the almost always upwards growth of BTC in the last year. However, now is the time when BTC is actually taken seriously by Big Players. Expect the China Ban to be followed by various other governments. Also don't disregard the Banks, Financial Institutions, International Money Exchangers (e.g. Western Union, etc), Online Money Exchanger (e.g. PayPal, etc) as most of them will lost a major portion (if not all) of their business; as BTC removes the role of middle-man via Blockchain technology.

I believe BTC can evolve from all of the hurdles if it could resolve it's own issues. Three of them are

• BTC transfer should be able to sent only to valid wallet addresses. I might be wrong but it seems if you enter a wrong wallet address (e.g. an ETH wallet), it goes through and ends somewhere in blackhole.
  
• It should improve it's network congestion. There has been transfer delays of days in some cases. Generally, it has been hours in the last couple of months.
  
• It should improve it's network fees. There has been increase in transfer fees which keeps evolving upwards. Meanwhile other currencies have lower cost and lightening transfers.
