that's an idea.
but based on my observation majority of altcoin specific (not board specific) spams are done by those who are holding a bag and want it pumped. these people don't care about or even have any signature. they only care about advertising their garbage. so even if signatures didn't show in that board, they would still spam there.

a better solution, in my opinion, would be to add the said board as a sub-board of [bitcoin] Development & Technical Discussion board. that way "technical" discussions are kept in one place in the same category and also it could reduce the spam since most signature spammers are already avoiding that place and also those interested or capable of "technical" discussion are already visiting that board.

maybe, maybe not. i think it could go both ways for them.
on one hand we have a multi million dollar company with a lot of power that is going through with the launch of their product and they are known to be successful company (Facebook!). so it would be an opportunity for these small fish to get in but on the other hand when the big players have pulled out (and there is a lot of them, i counted at least 7 big names) it is scary for others to go in something others have pulled out. they must know something that made them pull out.

there is no concept of "balance" on the blockchain. there are only transactions which have outputs that have amounts.

your wallet then calculates the "balance" for convenience.
when you have a public key, your wallet should check the entire blockchain for transaction outputs (scriptpub`s) that contain your public key (or hash of it). core for instance checks all script types, but other wallets only check the script type you specify when creating the wallet/importing the key/address. the sum of these amounts is that key's total received value and when each of these transactions are spent the amount is removed from the total balance of that key hence updating the balance locally in your client.

i would love to see a new "altcoin technical discussion" board but not coin specific, a general one for altcoins is the best thing to do since i wouldn't expect that much "technical" discussion in such a board and this is a bitcoin forum, creating a dozen dedicated boards to each coin would just crowd up the place not to mention that if an when these coins die, their board will remain here and become useless, whereas a general board would still be valid.

by the way the question you linked is more like a technical support not discussion.

you just got unlucky and created your transaction somewhere around the first yellow circle when fees were a little above 1 s/b but not that much then mempool started to grow. you specifically got unlucky when the fees dropped but not down to 1 s/b (down to 1.093) then it grew even more until the second yellow circle when your tx was mined




that would be a gambling game because it is not possible to predict it since you would be predicting the activity of thousands of people who are transferring bitcoin every minute.

if you are concerned with space then you shouldn't be running an Electrum server because it takes up a lot more space than a regular node because it has to index the entire blockchain so that it can fetch the data that anybody requests (transaction history, balances,...). it is a lot easier to run a regular full node and for space you can just run it in pruned mode.

i don't think they are going to give up on Libra though. they are losing all their supporters and partners these days but i am sure they will go ahead with it even though i think there is still a huge chance that it fails miserably, its centralization alone guarantees that.
maybe then, after the failure, they started adding bitcoin and showing support for it to revive their coin!

i don't think we can put a date on something like that. because for bitcoin to "overtake" a big payment system like PayPal it has to first become adopted by nearly as many people as that big payment system has and also it has to reach a much more stable price than this so that people would be more willing to spend it rather than invest in it!
and reaching mass adoption and price stability is something we can not predict. it could take a much shorter time or a lot longer time to get there. the only thing i can say with certainty is that the adoption will continue to grow for many years which means every day bitcoin will be used more for payments.

any fluctuations that are below 5% or in most cases below 10% even are not really worth discussing about and calling them "downtrend" or "uptrend" which is the case with "from $8,326 to $8,086 in the 60 minutes" mentioned here in OP.
the only thing that matters is when the price change is big or when it breaks some support or resistance levels. in this case when $8k itself was broken and price went below it, then it became important. and to be honest there is a lot of dump going on but it still doesn't look that strong to me and the "mood" is in my opinion mostly scared rather than being bullish or bearish. which is why the volume isn't that high and also why the price is NOT tanking even though there is a ton of dumping and price went below $8k it is still staying pretty close to it.

there is also a simple remedy that could cover all other possible fake copy-sites which i find very useful and that is the browser's zoom option for those browsers that store the zoom state per domain not for the whole browser (eg. Chrome and Firefox).

for example i have zoomed reddit to 200% so when i visit https://www.reddit.com/r/Bitcoin/ i'll get an easy visual confirmation that i am on a website i have visited before. but if i go somewhere else like https://np.reddit.com/r/Bitcoin/ i'll immediately see a zoomed out (default) size which is a quick indication of different domain.

then this is not the way to do it.
they should not reveal the idea to anybody. instead they should interview people and then hire those they choose, build a contract and even make them sign a non disclosure agreement and then tell them the "idea" after they've hired and paid them as employees.
otherwise, in this world where people seek open source projects and create them, keeping the idea secret doesn't mean anything!

if you are going to pay with anything other than bitcoin you can't post it in services board. you'll probably have to post it in altcoin marketplace board.

it is not clear what you mean by "signature contest", if it is something like make the best bbcode signature and you pay the best which you choose to use later then it has been done before so it is allowed.
but if it is something like "spam the forum with most posts and pay the top ones" then it is not allowed obviously.

it is just not possible for this amount be a "purchase" because you simply can not transfer $8 million (the fiat not equivalent) from your bank to a bitcoin exchange. the bank simply won't allow it. they are closing down accounts for a lot less values such as a couple of thousand dollars!

no, it was a spam attack against bitcoin network which they called "stress test"! basically at some point they tried to get others involved and try to flood the network with double spends. so they sent a ton of transactions to addresses with known private keys (which a lot of automated scripts are watching to steal their coins) and also a lot of coins to other keys which they released later: https://bitcointalk.org/index.php?action=profile;u=553487;sa=showPosts to cause a lot of traffic between nodes sending double spends. and to simply make people do the spam attack for them!

it is not unlimited, nothing in bitcoin is.
you are still generating a private key in a finite space (from 1 to n which is a little smaller than 2²⁵⁶) so it is limited by that number.

as for the second part it is talking about collision. or in other words a collision in the truncated HMAC-SHA512 digest which is not going to happen in our lifetime. it is the same argument about "can two person generate the same random private key".

are you trying to tell us that you who have been around ever since (at least) 2013 have been gullible enough to fall for all the lies that CW have been telling you?

both ATH and the lows this person is talking about are equally bad numbers to look at because they are both fake prices that are the product of overly excited people buying or selling too much respectively. in fact when you are looking at those lows you are also looking at a "bubble" but in reverse. a while ago i posted something about the reverse bubbles and how $3k (the low of this cycle) was in fact a reverse bubble. we later saw how it "reverse popped" as price jumped up $2000 in matter of hours.

dude "Yobit Officials" never read or reply to their personal messages, barely visit their own topics and barely answer their numerous scam accusations all over the forum. not to mention they also barely answer support tickets in their exchange. your topic's audience is only going to me regular members of the forum

their goal is clear too. they want to spend least amount of money and time, hire the maximum number of people to get the most number of spam posts to get the maximum exposure. all your suggestions are good but are against their goal!

so does this mean you will be controlling the private keys? or will users who create the wallet remain in full control of their coins by having their private keys and not giving you any access? because i don't see how that could work without it being custodial.

you are also not answering the other question: who is paying this "reward" and what is the befit in it for them to pay it?!

there has been some attempts but all of them are a failure before they even began because bitcoin is pseudonymous and you will never ever be able to look at the blockchain and claim coins are lost just because they have not moved.
for instance i have coins that i received in 2014 and have not moved them ever since (5 years) that doesn't make them lost, i still own the private keys. but in the eyes of many who just look at the blockchain it is categorized under "lost coins"!
