Why would you create a new wallet fo every transaction? This is an overkill. Create different level wallets. Long-term that you just put into, mid term and short term - that is it, maybe few of each. But when you make a lot of transactions you should use the same wallet. It's like you would create a new paypal account for each transaction you do. Any way I will check how long it takes for me to sync from scratch.
Once you have synced your node(electroneumd.exe) then syncing new/old wallets(electroneum-wallet-cli.exe) is very quick.
I know.. and this is not what we are talking about - Pilchard stated that he creates wallets for every transaction. For me, that is just way too much. You don't need that at all.
2nd thing he said that it takes 52 minutes to update new wallet to be up to date with blockchain. That is a different thing - you can have your blockchain updated but when you generate new wallet it will still need to scan entire height - currently 61524 blocks.
I just did a test, run a wallet from scratch, and sync took exactly 7 minutes. So not that long for my taste.
