Relocated old Coinbase account. Had 1.4 since 2016.

Decided to scroll down some really old emails on Gmail this morning and came across my Coinbase account I haven’t used in years. I had put ~$1,000 back in the summer of 2016 and got 1.4 BTC. I watched for a few weeks after that and became bored and dissociated myself with it completely after a while. Tried to login again during the winter of 2017 but I became locked out my account. Today I was able to gain access again after 7 years and was shocked to see BTC at $28,000 and very tempted to sell. Should I sell out or will the potential be greater in the future?
