I actually know what the pain is when you miss the train. I first heard about Bitcoin in 2010. Back then I was too naive as I did not bothered to investigate about it and promptly dismissed it due to thinking it was all but a scam. That was a big mistake as later in 2013 I got in and it was late... I ended up missing some good deals to it.
There are indeed lots of fraudsters that took advantage of the lack of information of people on Bitcoin and lots are got scammed. Those who distanced themselves from Bitcoin during the early years can't be blamed because the regulation at those times are vague and Bitcoin was infamous during those times as a tool for money laundering. Luckily, Bitcoin had proven itself today, and it isn't too late to join the community of Bitcoin enthusiasts.
I am glad I found Bitcoin way back in 2014, I never hesitated about BTC and now 100% of my online transaction is funded by, if not via, Bitcoin.
