That's right, it all depends on when you 'bought in' or started mining. I mean compared to all time highs in December 2017, Bitcoin has dropped 50 per cent. But compared to a little over a year ago it is still more than double.

So you're right - how much it impacts you depends on when you started being involved in crypto. I wrote an article about this recently, with a graph of how the top 50 coins have performed over the last 6 months: https://steemit.com/cryptocurrency/@hassy/cryptocurrency-price-changes-for-top-coins-since-december-2017
