2017 is the year of altcoins...
bitcoin will loose it's marketshare due to lack of innovation and real world usage adoption
30mins for confirmation? come on...
No new technology have everything fixed from the the word go! In the case of Bitcoin, we can attest that it has been stormed the weather for 8 straight years and looking rather even stronger. For now, there is yet to be an altcoin to displace Bitcoin and until there is one, Bitcoin would continue to wax stronger.
The delay in confirmation was owing to the crowded network and that wasn't totally strange, because the user base of Bitcoin these days is experiencing some unprecedented growth. At any rate, the delays have been taken care of, as would be expected along the journey of any pioneer.
