Back in 2013 my colleague used to continually try to ridicule me in front of the whole office for buying Bitcoin

I used to sit next to a senior sales guy in an open plan office. In 2013 I began investing in Bitcoin and made a number of purchases over a few weeks. I tried to explain to him what it was and why I kept buying it.

He would constantly speak down to me like I was an idiot being scammed, despite him not having the slightest understanding of how it worked. He was loud and condescending, and would deliberately make jokes at my expense.

I always told him we'll see in a few years how it ends up - I might be wrong and lose a bit of money that I was okay risking, but it seemed like a solid early idea to me. The fact I didn't care what he was saying would mildly annoy him.

Fuck you Rory. I'm still holding it, and I know you remember me every time you read about Bitcoin in the mainstream media now.

TL;DR - Do your own research and understand what you're buying. If you're still happy to go ahead, ignore the opinion of people who have zero knowledge of their own - they're just projecting their own fear and doubt onto you. You wouldn't take golf tips from someone who's never hit a golf ball.
