All of these numbers and formulas are wrong (except smooth, who is just giving rough numbers anyway). Risto's is admittedly labeled as a simplification. With 2.5% of the network hash rate, you have about a 60% chance of getting one or more double blocks each day. On average, you should get 27 double blocks per month. Every time you get a double block, you have a chance to get a triple block, so you end up with something like (per month):  a 50.4806% chance of no triple
 a 34.9481% chance of one triple
 a 11.6494% of two triples
 a 2.9219% chance of three or more triples
Again, this is just on an average month and obviously assumes your % hash rate remains constant. The chance of getting at least two blocks in a row is 90%. If you count only double blocks that are not part of triple blocks, the probability is lower than 90%. I haven't worked it out.

Pretty crazy to see XMR's marketcap being only 12.207 btc whilst it's ranked number 7 on coingecko.com. First coin having a lower marketcap is number 14, which is ftc. Talking about undervalued! Check it out: https://www.coingecko.com/en

Check it out: https://www.coingecko.com/enI think the (comparative) undervaluation is intentionally created by XMR's aggressive early emission schedule, so everyone can get a nice stack of cheap early coins and start bootstrapping ASAP. Thanks for reminding me to post this: https://monerohash.com/nodesdistribution.htmlMonero is a tiny newborn baby in terms of full nodes and global distribution (WTF Australia/India/Brazil? Get with it!). If Szabo or another cryptocelebrity blessed Monero with just half of the public attention he's directed towards ETH, node number could easily rise by an order of magnitude or two. Even without some famous person's endorsement, we have nowhere to go but up, up, up!

The math you used to arrive at 90% (.025 x .025 x 1440) is not how probabilities work. 60% is much closer to the actual number.

WTF is with these trolls? I posted to get on Polo for another coin Ive been part of since day 1 that I'd to see a XMR/VPN pairing and I get this shit. https://bitcointalk.org/index.php?topic=789961.msg13535318#msg13535318This looks like a concerted effort to keep the price down.

I stand corrected. I think the chance of getting one or more double block in a day, including any double that's part of a triple 1  (1  .025^2)^1339 =~57% Using exponents 3 and 1338, you have about a 2% chance of hitting a triple on any given day.

Now we're on the same page. Though, I don't think it's correct to subtract from the exponent like that, but I could be wrong.

Now we're on the same page. Though, I don't think it's correct to subtract from the exponent like that, but I could be wrong. Let's see if this makes sense. Consider a group of three consecutive blocks. Your chance of winning at least one is 1  (1  .025^1)^3 Your chance of winning at least two in a row is 1  (1  .025^2)^2 Your chance of winning all three is .025^3, or 1  (1  .025^3)^1. The sum of the exponents is constant.

He makes some very valid points and he is of course right about the negative impacts of the 1 MB blocksize. He is also correct in saying the "bloat" is not the issue, in fact the small blocksize in Bitcoin may have led to the massive concentration of the Bitcoin hash rate in China effectively allowing the Government of China to control Bitcoin. On the other hand I do not agree at all with the criticism of people such as Gregory Maxwell, who I must say has also made many very valid points on the matter of scaling Bitcoin. The simple reality is that the Bytecoin solution of adaptive blocksize limits without a tail emission is also a prescription for disaster. The problem with Bitcoin is that nobody has found and it may well be impossible to find a way to develop a fee market, in the, absence of a block subsidy, that does not over time converge to one of two undesirable results: Fixed blocksize and infinite fees or infinite blocksize and zero fees. Mike Hearn has made a very persuasive argument as to why a fixed blocksize and infinite fees is such an undesirable outcome; however I am sure that Gregory Maxwell can make an equally persuasive argument as to why an infinite blocksize and zero fees is an equally undesirable outcome. Maybe the real reason why there has not been a solution to Bitcoin blocksize debate is that a solution may in fact not be possible, if one keeps the 21,000,000 maximum number of XBT limit in place, rather than because of the personalities involved. So in all of this where does Monero stand? Well Monero is the highest capitalization coin that has solved this problem in a pure proof of work coin. My philosophy on this is that when one takes care of the long term the short term will take care of itself. On the other hand focus on the short term and expect grief over the long term. Monero has taken care of the long term, unfortunately Bitcoin and for that matter most other crypto currencies have not.

The problem of hash concentration could still be something that needs to be smartly tackled. Otherwise XMR has got some pretty solid design for a crypto currency. I am a big believer in PoW but hash concentration is a potential problem (down the road) On the markets, seeing some minor positive action even at this hour for a change.

The problem of Bitcoin hash concentration in China was paradoxically a direct result of keeping the blocksize small. This happened because ASIC production is most economical in China. With an adaptive blocksize limit in Bitcoin this likely would not have happened since The Great Firewall of China would have placed miners in China at a very significant disadvantage due to latency. This would have forced Chinese ASIC manufacturers to sell their devices for export. The lesson I see here is that a well designed crypto currency will route around censorship and drive mining to those jurisdictions that do not engage in Internet censorship. Monero is way less vulnerable here since it is likely that both China will be the most cost effective place to manufacture electronics and will also continue to censor the Internet. Well the myth that "bloat" leads to centralization has been debunked. Edit: Monero has also other ways to mitigate this risk such as an ASIC resistant algorithm, and initiatives such as smart mining; nevertheless I do agree that this risk will need to be addressed and minimized.

An article about privacy that mentions ring signatures being "promising tech." How exactly does that mean "the beginning of the end" for Monero? Because Vitalik wrote the article? Don't worry. He still has to implement his 12 second block times and secure proofofstake model, first

Miner concentration in China is the result of market forces, and not any more of a "problem" than developer concentration in California. China may become XMR's biggest market, so it would be great if you stopped emulating Hearn's Sinophobia. The Yellow Peril stuff was funny when Hearn did it in his recent Opus, immediately before walking out on Bitcoin like a spurned lover being told "Sorry, not tonight dear." But if you're going to hang around for a while, I'd appreciate you not insulting/offending/alienating citizens of the world's largest economy.
