I invested first time in 2017 when BTC was around $2500. I know about BTC way before it when it was about $200 but never trusted it.  One of my friends suggested me at that time to to buy one but I just ignored his advice. Then I suddenly realized about its growth and potential of it in may 17 and start researching about it.  First I was thinking of buying a miner but then I dropped that idea and bought around 0.45 BTC.
