The reason that I’ve missed Bitcoin is because of skepticism and listening to the negative opinions of others that it’s nothing but a scam and hype. This is why I have regretted until now in not buying some BTCs while I could still afford even if I am struggling off my finances that time.
The same as what I experienced, I got to know bitcoin in 2015 and at that time I believed more in negative news from various sources so I didn't invest or earn bitcoin from various sources which at that time were easy to earn bitcoin.
