I am guessing here, but are you using a desktop wallet? You need to specify what upgrades you are talking about. The Bitcoin software {protocol} are constantly being upgraded and these upgrades
are distributed on GitHub. The upgrades do not influence the price, but if these upgrades are controversial and people struggle to get consensus, some conflict will flow through the community and this
will cause uncertainty. Other implementations like XT and Classic compete with the Core implementation and the fighting between these camps, will influence the price. Investors wants stability, and
a long drawn out fight will definitely influence the price.
