What was the best/most interesting thing you bought with Bitcoin, when, where you bought it and how many Bitcoins it did cost? 
One of the best thing I've bought with bitcoin is a motorcycle, and it is a gift for myself for my hardwork
way back November 2017. I had to sell my bitcoin in exchange for fiat because in my country, that particular shop doesn't accepts bitcoin as a form of payment. So I'll use USD for fiat reference in this case.It cost me about roughly 1,460 USD (0.0038 btc) that time.
Investors who managed to sell Bitcoin at the end of 2017 can indeed be said to be lucky, because entering 2018 Bitcoin immediately fell very deep.
I'm glad to hear that you can buy a motorcycle from selling your Bitcoins in 2017, which is a very good decision in my opinion. Because most people
when approaching the end of 2017 are getting greedy by continuing to buy Bitcoin, even though the price is already very high. That's why so many
people suffered losses because they panicked seeing the Bitcoin price fall after successfully reaching the ATH price in 2017. Actually, I have bought
a lot of things from the profit I got from investing in Bitcoin, therefore until now I continue to collect as much Bitcoin as possible, because I believe
the price of Bitcoin will continue to rise, so I can continue to buy the things I want through the profit I get from Bitcoin.
