If you are holding your bitcoins with the expectation of bitcoin will be hitting main stream adoption one day so that you will easily buy groceries for direct BTC payments and pay your gas bill with BTC, your dream will get fulfilled one day but after that you may regret for spending bitcoins for lesser value or for silly things.
Nah, I don't know If you believe that there's actually people who has been spending their Btc in a day to day basis. Though the amount isn't that huge, but they're actually using Btc to pay for service or for a booking. And they are totally aware of the fact that they might been paying more than just the usual price because of Btc's high volatility, but these people are what you called Bitcoin enthusiast and a Bitcoin supporter. These people doesn't only want to make a good profit out of its volatile nature, but also wanted Bitcoin to grow and become a mainstream payment option in the future. Bitcoin is supposed to be used as a currency to create a greater adoption.
Yeah because of those people who have been using Bitcoin on day to day basis the community becomes larger. If everyone keeps using Bitcoin as a currency a lot of institutions will now gradually accepting it as payment. However, the fees could really kill us sometimes and that sucks I hope that sooner this won't be a problem. Those fees are the problem why everyone having a doubt to use it as a currency that is why they choose it works as an asset. Being used in day to day transactions or as assets it doesn't matter you could choose whatever you want to do with it as long as the community is getting bigger that is all matters.
