Have you ever tried to meditate to get more results?
No, I haven't, and how would meditation give you more or better results? that makes no sense.
"Meditating for HODL strategy" I haven't tried it either, especially not as an "strategy" (?), but I can see how it can be helpful, for instance, meditation would've helped a lot of people last week during the massive drop we saw in the market (people were freaking out like crazy), so creating a peace of mind and getting some positive energy around you could definitely be of help in extreme circumstances.
So yeah, meditation could be a great practice for those who get easily nervous/anxious when they check out the charts, but to use it as an actual strategy to 'hodl' ? I'm not sure about that.
