Still the wallets like coinbase and blockchain.info wallet also going to update to segwit later in this year so we can expect the transactions will occur faster than the history but I don't think it will make any big impact on the prices for now because many countries regualting the crypto currencies so it takes more time for the recovery process.
Having bitcoin function as intended will definitely have a positive impact on the price, but it won't suddenly jump from a low price to a high price, it just means that there can be a more steady increase without people being able to easily attack it because it's useless.
Regulation isn't really holding back the price either, only uncertainty as to what shape this regulation will take, a lot of that has been cleared up in the last months and is fairly factored in to the price.
Bitcoin prices took a giant leap past $10,000 in the trailing 24 hours.
going back to where bitcoin price should be, which was actually a small rise from previous price at $9500ish is not a "giant leap". a giant leap would have been if price went to $12k-$13k instead of this and kept on rising.
and i don't think this has anything to do with bitcoin core new version release!
My thoughts exactly, it's barely an increase at all and almost certainly is completely independent of the release.
