I fomo bought $200 worth of bitcoins today from the $5000 price tag. After all those years, I still fall for this old trick.
I bought some from $15k too after all. $5k looked very cheap compared to that.
Long-term you are very likely to be fine.
I have told my own story before.. not without exact details, but throughout 2015 I had been relatively reserved in my BTC buying so I had a bit of an extra stash of money that was just waiting to buy BTC if the price stayed flat or if it went down.
So when BTC prices shot up from upper $200s to $500 in less than a week, in early November 2015, I ended up buying very close to the $500 price with a large portion of my reserve cash.. almost all of it, if I recall correctly.
BTC price then dropped back down to $300 and largely bounced around between $350 and $450 for more than 6 months... so that one dumbass FOMO buying of mine did not become profitable until after the end of May 2016.. when BTC finally went above $500 again, and never to be revisited.
That mistake continues to come to my head when I think about how to approach my BTC, and I wonder whether we can really learn how to buy on dips, accumulate BTC and strategize our attempts to be profitable without having some of these kinds of experiences that really teach us on a very personal level.
My point, in part, is that 2015 was a very struggling year for me in terms of cashflow, and all year long I was building my fiat cushion, and really that fiat cushion was to buy BTC, but I was always anxious about having enough of a fiat reserve and probably also feeling a bit shell shocked too because I did not always have money to buy as much BTC as I wanted when the BTC price would dip in great ways from time to time and more than I was prepared for.... So, yeah, I blew at the local top of $500 nearly all of that built up armored fiat that I had in my reserves.. and kind of shut myself out (partially handicapped myself) of doing as many things until those coins became profitable again... almost 7 months later.
By the way in early November 2015 when I bought at $500, I was calculating that I was getting out of the negative zone, and my mental state was pondering that I was never again going to be able to buy BTC under my average cost per BTC because I saw the BTC price going UP and UP and UP... stupid and a bit embarrassing when I think back on my own, in the moment, excitement based reasoning.
