Question about double spending and the "Bitcoin puzzle transaction ~32 BTC prize to who solves it"
If someone eventually managed to brute force Puzzle number 64 (and beyond) can't someone who's monitoring the keys just use Pollard Kangaroo once the public key is broadcasted and also sweep it with a higher transaction fee since double spending is still an issue with Bitcoin? If thats the case how can you prevent someone from sweeping the same key if you're both in possession of the same private key?

Is there a confirmed case of double spend like bitcoin?
I found an article that explains why you should wait 6 confirmations for bitcoin, but I found nothing about that for Monero. Can we be safe on 1 confirmation? I understand the 51% attack, but that is highly improbable (are there statistics of such cases?) and anyway will not happen for small transactions (under 1000Euro). What about cases of persons that lost monero because they did not wait for 1 confirmations or more. Did this ever happen? If it never happen why does monero put me to wait 10 confirmation before using the money again, why not lower that? BTW is it possible for monero cli or gui to also check and worn in case of a 51% attack or this is not possible? I see all sorts of stupid articles about Monero used for darknet etc but no article that say:
use monero because of the low fee
use monero because of the fast confirmation
use monero because you do not want anyone to see how much money you have (this is even in contradiction with the new GDPR, bitcoin does not respect GDPR but monero does)
Anyway I really like Monero for all that it stands for and please stop this association with dark net because I see a trend here that is becoming very bad on the long term. If you see 1 article no problem, but if you see 20 you start wondering and this is really making monero look bad, and it really is not.
[PSA] New Bitcoin/Crypto Users watch out (Double Spend Scam)
Experienced users can ignore this, posting because it's been tried a lot on me and people I know in the past weeks. How the scam goes is that the scammer asks to buy stuff with Bitcoin and goes first and then tries to get the seller to send the items immediately when the transaction is still unconfirmed saying stuff like Bitcoin is irreversible. The scammer sends same coins once with a low fee to the buyer and once with a high fee to himself, the high fee transaction gets confirmed while the low fee one gets discarded from the Bitcoin mempool. TL,DR: if you are selling items for any crypto and going second, always wait for atleast 1-3 confirmations before sending items
