interpreting the decimal point wrongly. The reading on the Twitter entry is 12,15$ (12.15$ in the image), where the separator is a decimal point
I would add that I've seen bots interpreting the decimal point better than this.
If the tweet would have been about $12.150 then OP could have had an excuse, but as it is, nope...
Nonetheless, if you’ve been holding since 2012- good on ya 
I'd guess that if he would be holding since 2012 he would know the price levels from back then and not mistaking at such level of magnitude.
