Holding bitcoin long is a very good way to make passive money but it is not fast at all you need patience and your money is stuck for that time being.
So if you don't need the money right away do it and laugh while you profit from the value increase
That is right. If you hold the bitcoin since 2010, you might be a millionaire now if you bought some then.
If you are just bought some you will not be millionaire but if you buy even 50 btc in that year you can be millionare here in my place but in other place like US 50 btc is not enough to be millionaire i think 1700 btc you can be millionare that you can sell it right now. .
