By that time comes, I can say that I am using my bitcoin in real life.
A pretty good fella's plan, because if you spend all your btc got on now. Then you will not get an advantage in the future, but if indeed you need to have the funds then you must also use it, yet with a record you should also leave some BTC for savings
Its always good to sell a part of it when you see higher price and rest should be saved for the future as price may go higher in future which will you to earn higher profits.
the point is you have to save your bitcoin and sell when you have a need that is really important and very necessary.
so you can save bitcoin up to future. and this is what I do, not a lot to spend, but there is time to spend it.
Saving is good for the future as it is expected that price will go higher, but I think I will keep on spending it on trading to multiply my coins to grab higher profits.
