I have read different threads like this but to participate on this thread, you can have my answer even I'm not a newbie but I'm in bitcoin since early 2010.
What will I do if I have 1 bitcoin?
If you will be giving me now 1 bitcoin that is worth $38,534 at this recent price, I will keep holding it until it will double the price. That could be a great help on us, I can even build a house and buy a car with that amount but I choose to hold it because I believe on bitcoin that will increase more after more than 2-3 years. We have been witnessed different ATHs on bitcoin and we know there's more waiting ahead, it's worth it to hold some and it's fine if you will cut some profit maybe 25% on it.
