I hold it like that for strumming and picking but if you feel more comfortable holding it another way, you should keep playing on your own way.

in my opion
which ever way it feels better for you
liek the other person said ithis is just the proper way
doesnt mean its teh only way
I like it for picking, and I think Im gonna force myself to get used to it for strumming. Only bc the way I used to hold it for strumming/picking it would always twist between my fingers causing the "round part" to be facing the strings instead of the correct part. thats actually why I looked up the vid haha, but when I hold it like that it doesnt spin at all.
Personally, i like to use the shoulder of the pick (the rounded part) instead of the pointed part for strumming and picking.
