Its interesting to observe that replies from 2014 people use to spend their btc in food, pizza, games, online shop... But now people are hodling , because now btc became more than just a coin, its a investment .. People are now believing and betting on it because they know how pottencial this crypto is!
I actually still use Bitcoin for day to day purchases when I can. I just end up buying more BTC at the end of the day. I think using BTC shows that people still use it so merchants wont remove it, but I buy the BTC back so I can hodl.
