Doubting Thomas's

So I had an interesting discussion with a friend the other day who at the time when I first was speaking to them about Cryptocurrency they laughed in my face and said I was foolish dabbling into it, that was at the time a few years ago when BTC was breaking into the 10,000 GBP mark and now no surprising now when the value has almost trebled they are suddenly interested in BTC and crypto who else is having a resurgence of people hitting you up for advice since the surge in BTC. Not that I would say I am having the last laugh but more of a I told you so and shame you didn't jump in when you were told the first time around.
