Of course the most important is investors who influence the value of bitcoin. The higher the demand, the higher the price. This is the same as if we trade.

I see a lot of people that are hoarding 100% of their bitcoins, because they believe cutting off the supply, would be enough to increase the price.

Would it not be better, if we increased the demand by increasing Bitcoin awareness and convincing more merchants to offer Bitcoin payments?

A 100% hoarding strategy is more harmful, because it cancels all the good work that was done to get merchants to accept Bitcoin as a payment option. A merchant will stop accepting Bitcoin, if their is no demand or transactions being generated for their business from the Bitcoin payment side.

We should actively encourage local merchants to start accepting bitcoins and then we should start supporting them.

Just buy back the bitcoins that you spend and you will be fine or use money that you would not have hoarded and buy the goods or service with bitcoins.

Adopt a 80% hoarding and 20% spending strategy and we will see a massive increase in Bitcoin adoption    

Blockchain is a good technology that will be use as a tool of transparency to every transaction being done. The government should know and develop a system like this on their system. This will eradicate corruption or transactions being made under the table because there will be a transparency on every transactions and how much money is involve. The budget of the people will be obviously utilize to its intended purpose. Would you agree with this idea?
