However...

WHY would you INTENTIONALLY expose yourself to the POSSIBILITY that your RNG MIGHT not be as good as you'd like?

WHY would you INTENTIONALLY expose yourself to the POSSIBILITY that a weakness in ECDSA MIGHT be discovered in the future?

WHY would you INTENTIONALLY reduce your own privacy AND the privacy of those that you engage in transactions with?

Especially, when you can improve all 3 of those situations by simply generating a new address for EVERY transaction? A business wouldn't re-use an invoice number, why would you re-use a bitcoin address?

Yeah, I admit it's lazy. I need to tinker with Electrum more. I imported a private key into Electrum-LTC and spent some LTC. For whatever reason, by default, after I spent a portion of the LTC, the Electrum-LTC wallet sent the leftover LTC back to the original address. I'm assuming if Electrum-LTC is a fork of Electrum, they both work similarly for imported private keys.

Having said that though, I have my private key for my BTC address printed out. I plan to spend some BTC over the next several weeks (or months). At the very end of my spending, I then plan to move the remaining BTC to a new address so that it cannot be hacked. But during the next few weeks and months, it's just a hassle to generate a new address each time, and then record the private key for each new address (hardware wallets are all sold out around the area I live). As for the privacy of the destination address, it's a BTC address for my account on an exchange so I don't care too much about privacy.

That's why I was wondering what is the possibility that somebody can hack my address over the next several months if I reuse it. If the probability is extremely low, I don't mind the risk I take over the next several months, provided that at the end of my spending at the end of the next few months, that I move my coins to a new address and don't spend from the new address.

In your opinion, do hackers even have the technology or has a weakness in ECDSA been found recently such that reusing the same address over the next few months is susceptible to being hacked?
