but if you want to make a cold storage it will be quite harder to use your coins for buying stuff etc.

If you want JUST to hodl ... cold wallet would be good option.
So what is your purpose? Keep your coins safe of rotate them

spend, earn, etc.
If you intent to spend some coins on a regular basis but dont want to go through an offline txn for each purchase, keep most of your coins in cold storage, and a few in a hot wallet.
Well yes, you are right.
