I thought you're want to say coins in centralized exchanges aren't yours, but actually
it's a skill issue thing.
I don't buy any kind of psychological thing, if someone want to hold for long term and they have a skill issue to not able to control himself, then use
timelock transactions, the problem will be solved.
do you also do this and does it really work for you?
I do nothing and I've hold for 3-4 years.
