<...> even though my achievement of becoming a Satoshi millionaire may sound as a small achievement to most people here. I am super excited to have become a Satoshi millionaire today and am going to hold on to this and also accumulate more subsequently.
It does sound as a small achievement to some of us, but what is important is your personal situation, and the path you are on. If this is a first milestone that makes you feel satisfied, good for you.
Keep accumulating little by little. If you HODL, the million satoshis you have accumulated today will probably be worth a lot more in the future.
What I would recommend is that if you have a good amount in the future, take advantage of the bull market to spend even small parts of it. As famous as HODL is on the forum, if no one spent bitcoin for payments it would be worthless.
