I always wanted just 1 (still do), but back in 2010 I was just going to spend £100 and see what happens. It seems in the US the people who did similar to what I wanted to do in varying forms made good profits (and had an interesting ride).
This is different from 'speculating' (e.g. 'oh I wish I had actually bought some') - I had full intent and wanted to buy them, but just the barrier to entry due to UK regulations were very high. I even tried to arrange peer to peer transactions through reddit or in person but they also seemed difficult. Most people I ever met in person who had any didn't want to sell due to the belief of the ever increasing price.
