Bought my first around $250 in the beginning on the 2013-2014 bubble. Price went to $1100 and dropped back to $200. Keep on HODLing

If I would have known for certain that the price would be as it is now, I would of course have bought all I can get my hands on. But as we are all just humans with no time traveling skills I don't feel annoyed that I have invested only moderately. I rather feel lucky for getting so much back from my smaller investments.
