For, I am only familiar with "Bitcoin pizza day" which represents the day an individual bought two pizzas with over 10,000 Bitcoins worth $40 back then, and I have no idea about the rest. But I think there are some days here that make no sense and I don't see any reason why they are important to Bitcoin in any way, such as Independence Day, Bitcoin Infinity Day, Bitcoin Whitepaper Day, Bitcoin Logo Day, Bitcoin Day, and HODL-day. Because I think these days makes no sense, but it would have nice if only had you explained it a more better
