Good luck to me and everyone play dice.

Choose the right time to hold bitcoin or altcoin is based on your experience. You must take an overview on market to make your own choice.
Example: When btc up and down suddenly, alt market will down, this is right time to use btc to buy the dip and wait alt market recovery to earn more btc, then take profit and wait next chance.
Or another advise is: Buy when red and sell when green, repeat it!! Good luck!

Cold storage is best choice for me.
Or another way is:
Download btc wallet for PC, then make 2 back up data file and copy into 2 USB, then put them into 2 safe place.
There are two choice if i were you.
