I can only concur with you. The two coming years will be indeed golden, for the simple reason that there will be much more people coming, a wider acceptance, and I hope, let God grant us that, finally a technological upgrade to finally get out of the network saturation problems.
Yes its true, many have accept bitcoin and slowly it becomes an easy transaction tool for all of us. Bitcoin will be a very good digital money for transactions because there is no big tax in sending process.
blockchain technology will be very useful for all of us in the future.
