Re: If you have a lot of bitcoin, should you spend it or save it?
If i have 5 to 10 bitcoin i will convert it into fiat and spend them all. Buy all the needs of family ,start a new business and live a happy life. Im not a holder and i only losing the opportunity if i hold my bitcoins for a long time.
You already said why you wont be holding a few bitcoins. 
If your plan is to sell the coins then you wont be able to accumulate for the future,the best plan would be to start investing in promising projects and make sure that you will wait till you attain a good profit and then think about selling and setting up a good business.
