I have a "core" holding in bitcoin. A few BTC I will not sell (or spend) until the really big pay day. A couple are digital and one is a physical CASASCIUS bitcoin that has never been redeemed. I will hold that coin until I can auction it off at one of the big auction houses some day. :)

Any other fractions of BTC I buy or sell trades around that core position. Looking at it that way it is no big deal to me if I miss this entry or that entry as I will always have a long position in Bitcoin. I bought into Bitcoin when most people didn't know what the heck it was because I saw the future potential of BTC. My opinion has not changed. It has only been reinforced with all the crypto mania of late.
