The reason I believe I haven't lost even a single penny is because I believe you cannot loose when you don't encash.
Therefore I still believe holding for the long term can actually help you .
When the price of ETH was 0.10 BTC, I watched a lot of videos on youtube and in those videos or saw people say they bought a lot of ETH for the price of 0.10 because the price would go up so much, look more than a year now. ETH is 0.021 and it is dropping and from what I see the price has no chance of rebounding to 0.10 BTC. Bitcoin is a good investment, but you should always have a good strategy even if it's Hold for many years.
