Personally, I would hold on to bitcoin. I will wait for the price to go up and then I will sell them.
How can you tell the price is up?
Well if that is your method then so be it. Holding is nice but rotating is much nicer. You will got my point if one day you will need money and your saved bitcoin is your last hope.
When the bitcoin price was $80, I thought bitcoin price peaked. I used the bitcoin to pay for phone bill. That turned out to be 3 times too expensive if we use today's bitcoin price to compare.
I'm interested to know what phone provider was so far ahead of the trend as to be accepting bitcoin as a payment method!
