As a BTC holder I can say that it is necessary to find a certain balance between a long-term investment and using BTC as the currency for paying for goods and services. What actually prevents many to spend their BTC is the fact that they don't really have anywhere to spend (at least not locally), and if they decide to buy online from other countries they may face extra costs in the form of VAT and customs fees.

All those who want greater availability of retail outlets that accept BTC at the local level, need to do something about it. It is not difficult to send an e-mail to the seller and propose to enable BTC as a payment method, as many do not even know that such a thing exists at all.

BTC as a currency and store of value is something that can work, but everyone should contribute to that end.
