I would sell 1 Bitcoin to make a nice holiday with my family.
With the other Coins, I would split them up. Maybe look for a real investment, like assets of a company, or a house for rent, or maybe invest it in your own work if u have the possibility for it. So it is safe and can grant u a stable income without any further risks.
The other half of the Bitcoins I would just hold them and look how it is rising.
