Welcome, try to give less details about your personal life because you want to learn and not start an activity or something that needs to reveal your identity, and since you do not remember the username, can you remember the events related to Bitcoin during the year 2016? It will be interesting to listen to your stories because you know things that most of us do not know.
Oh sorry about it mate.
Well way back 2016 I can recall that the price of bitcoin that time is around below $450 (not our main currency just converted it from where am I), I did buy Bitcoin way back on time from our local wallet/exchange just to invest HYIP and Ponzi scams

, I do also earn it by creating some logos and micro task coming from my online friends and they are paying me in Bitcoin(roughly $20 ) well that's too big that time as I am coming from poor family. Then that is the time I can recall that there are no merit system here in the forum , and also the era of Bounties raises(new tokens coming out and this is the time of ICO) which I can recall that I've joined some of it, this is where Bitcointalk having problems with spammers and shit posters(I admit this) and plagiarism which lot of higher ranks saying some suggestions to prevent it and the merit system was push through , that is the time I think I was gone from this forum. I can remember yahoo62278 is the best signature campaign manager before that I've known as most of the Bitcoin signature campaigns is he is the one managing it. There are a lot of giveaways of Collectible tokens before that the members here giving away and what's best is that they shoulder the expenses on shipping. Also unlike this year that a lot of exchanges closes before most of the exchanges are legit I mean we don't have issues that they go bankrupt and one of the famous exchange before is Bittrex (it is not the same UI now than before).
I forgot other events happened here in the forum before but I'll edit this if I can recall more

Oh, also I forgot that every April Fool's Day (1st of April) Theymos is doing some kind of trolling before. I just can't recall it, but Theymos is posting that if you do not achieve those required posts, your account will be deleted. I am not really sure if the merit system was also kind of done as a trolling before.
