Probably convert it to cash and setup a stock portfolio
Thats not a good idea for me because my plan is to make it increase more.. better to invest it something useful online trading or start your own business is the good idea to increase the amount of bitcoin so that you can earn more in the future..
You mean to say real life business? And if you want to start real life business then you need to convert it to fiat first and then invest, or else you always have an option to go for trading.
