I know I've made the right investment when I see the value of my investment going down and does not feel worried at all, instead I am waiting for it to go even lower to buy even more. There is this assurance inside me saying HODL instead of trying to cut losses, every crisis is an opportunity. It's not a feeling of self deceiving saying it will rise again but a feeling of confidence saying it will rise again, just HODL. I feel HODL is a very strong word, though same as hold but gives a sense of being a part of a community, the community that has the same vision and hopes as you.
