The future with Bitcoin is bright

[KingsDen]

Will buying and hording for a long time profit me?

That is the right thing to do. Now is the stage of accumulation. Buy as much as you can and remember not to invest more than you can lose. Because bitcoin can go deeper from here at anytime.
If you hodl from now till the first quarter of 2024, you will see a nice profit that will make you smile.
