Not greed but rather seeing this on making cost averaging even though risk is getting higher since you do throw up money even more but we know the chances of recovery here on crypto space specially with bitcoin then those buying on gradual basis would surely pays off.

On that way it would really lessen out the money you had lost when you bought on 60k but actually if  you are really going for long term then this wont be a bothersome situation for you but instead you can simply hold up until price recovers.

Buy the dip and that should be always on your main consideration that you must have some reserves.
