It is correct that we had a massive bull run in the last 12 months. But you are looking at a time frame which suits you.
For it to be a remarkable investment, you must look at multiple 12 month periods, including the drop 3 years ago.
the 3 years ago drop that you are talking about is just a drop out of a bubble, and it was not even the first price bubble! there have been as big price bubbles as that one before but since it was along the highest price and also the scam exit of MtGox, everyone remembers that and they keep mentioning it.
the same rise meaning a big % rise then a big drop has happened before and then from 2013 onward bubbles have also been happening but at smaller % so they usually go unnoticed or called as whales dumping.
