I do think that there will be a bunch of speculation on BTC, but I don't actually think it'll adversely impact alts to a great extent for some reason.

I wouldn't be surprised if there is anticipation of a price drop that is counteracted by a rising alt price. However, once there is stability with BTC, I think that's when there will be a significant crash with many alts.

However, infrastructure is significantly more limited than it is with BTC and a lot of other alts are quickly catching up. LTC still has a sizable edge, but that gap is closing rather than expanding.

Though in fairness, you write this as ASICs are just now starting to take over the network. We're going to have a much different looking picture at the end of 2014. When you look at Litecoin's network difficulty and hashrate, it dwarfs all other alts.

Litecoin's network will never have the hashrate or difficulty that Bitcoin does, because of Scrypt. That limits the amount of hashrate that can be squeezed out of ASIC hardware, relative to power consumption. But in relative terms, Litecoin's network over the next year will likely grow to become just as secure as Bitcoin's is, today...if the current momentum is any indication.

Bitcoin looked stagnant for a long, long time before ASICs hit it, and more attention started getting drawn to it. That attention came from the investment being made in its infrastructure. That vote of confidence was essentially what catapulted it into the consciousness of venture capitalists and investors. So the premise that Litecoin is somehow dying a slow death, while hundreds of millions are being poured into hardware infrastructure seems a tad premature, to me.
Sorry for the lack of response; I was more referring to infrastructure in terms of the usability of LTC (such as merchant acceptance). Multi-payment processors and quicker adoption of other coins in various crypto-currency marketplaces have quickened, so it's beginning to take away from that secondary strong suit that LTC has had.

As for ASICs, I really do see it becoming like it is with BTC; LTC will likely be the standard sCrypt ledger and I don't anticipate it falling by the wayside to any other sCrypt alt.

My apologies for the confusion, I tend to bucket advancements in market penetration as part of the infrastructure and hardware infrastructure as part of security.

Never! Just keep hodling them. Tongue

Okay, seriously...Like someone mentioned, this is pretty much gambling.

There are tons of formulaic approaches that people take, but sometimes simply listening to your gut when it seems like something might happen works too. Although buy low, sell high is the intent, sometimes when you miss a pump and the long-term trend is negative, you have no choice but to take some losses. Just don't "panic" sell if you can help it.

Holding coins for stake is risky business and if you're looking to make any returns the compensation should match the risk.

If you're going to hold coins for stake the coin should have a stake greater than 25%. If the coin has good devs and a decent community, it is possible that you will get a return on your investment. Another note about 25% - it is also the point where you can actually see the benefits of compounding interest.
I do agree that holding coins for stake is implicitly a risky business due to the nature of volatility in the crypto-currency scene being doubly compounded by the amount of time needed to create stake.

I am curious how you derived 25% as your set point. If you are willing, could you share your mathematical rigor behind this?

I agree completely about risk. That's why I've stated many times in my posts that this is a risky plan and only with money you can stand to lose.
But I do it.


NO COIN WITH STAKE <25% IS EVER WORTH BUYING JUST FOR STAKE.

Do the math: coins * (1+Yearly Stake %/365)^365

Yes there are coins with a stake period of under a day, but it is most likely that your stake will take longer because of the network so staking oce a day is conservative. If you do the compounding math, the 25% mark is where you actually start to see the benefits. So all those coins where stake is 10% or less compounding every 6 to 8 hours...at the end of the year you will have your coins plus that 10% or less.

See my previous post about compounding interest with the formula.

coins * (1+Yearly Stake %/period)^period

If you have stake at one month and you have 25% stake you get roughly ~27 coins. Not great, but better than 25... And anything lower will only give you the stake percentage. The higher the stake and the shorter the period the better the compounding.
I was more looking for how you derived that 25% stake overtakes the risk assumed by holding a PoS coin and selling at highs and staking at lows. You just gave me the effective interest rate of a nominal interest rate compounded n-thly.

Whenever I've looked at staking via a market perspective, I look at it as akin to a derivative pricing model so that's what my request was more geared towards. So if someone places bands at upper and lower options, I could take the partial derivative (i.e. kinda like in Black-Scholes fashion) of [δσ/δt-(1/(σ(T-t))][(r/σ^2)] where σ is compounded volatility, t is the starting time of staking, T is the time where stake is sold, and r is the given effective interest rate, and look for where the intersect between perceived risk and reward lies. When I've priced using "slower" models, I get stake at 15% being reasonable to overtake the assumed risk. For "faster" models, this drops slightly to 12%.

Could you expound on your methodology for showing that 25% is the point where risk and reward meet?

lets understand marketing

infrastructure is the key for investors and businesses to adopt a coin

I run a business and as yet my customers do not understand crypto

If i was to offer them crypto i would select a coin that has a strong infrastructure and investors


btc and ltc both have enterprises supporting this, why is there asic machines on sale if the market was not there, why is there atm's being built if the markets not there

please provide me with another coin that has the infrastructure to support my customers cash exchange and a network that is very hard to fall down like other altcoins have after a few months

This is very true, relatively speaking, LTC is the only other ledger that is at least significantly secure, especially with ASICs (excluding the possible pool issues). Frankly, the security already established for Bitcoin and the growing security for Litecoin are going to be difficult to beat (and that's what it'll take to overtake either coin). It seems that people keep forgetting that the alternate crypto-currency scene is a fringe of an already fairly fringe scene; so what is great for them isn't going to necessarily be great for a majority of others.

It surprises me that so many people here think that an anon coin or a coin with a ton of nifty features is the bee's knees. Last time I checked, using those other protocols still requires a significant amount of technical knowledge or familiarity. Do we honestly think the majority of people would look for something like that as the alternative to bank-owned fiat? As I see it, the place for improvement is not in anon or new algorithms or nifty new features, but in ease of use and ready accessibility (such as in a improved GUI experience like someone had already mentioned).

However, infrastructure is significantly more limited than it is with BTC and a lot of other alts are quickly catching up. LTC still has a sizable edge, but that gap is closing rather than expanding.
247  Alternate cryptocurrencies / Altcoin Discussion / Re: Litecoin Is NOT Dead (It Is Just Dying A Slow Death) on: June 23, 2014, 06:35:06 PM

I will give them (well… Warren) a bit of credit for improving some security issues on both Litecoin and Bitcoin, but they do not see the glaring issue in that the end users don’t actually ever see these improvements. Nor do they particularly care… what I mean by that is… Have any of you ever had a problem because of a security issue in the Litecoin/Bitcoin client? I would be surprised to hear one person tell me yes they have, as after using it for years I haven’t and most cases that pop up seem to be user error.

However, with a technology so new and relatively "fragile," even one significant security flaw will implicitly mean death. Think about it, when was the last time you've heard of the central system of a bank or brokerage being broken in to? By this I mean, someone directly siphoning funds from the internal system, not someone doing an XSS exploit and retrieving user information; the later is akin to someone getting their PC hacked which happens quite regularly in the crypto-currency realm.

Due to rapid technological advancements and the competition being innovative and forward thinking (seeing a pattern here?), companies can become obsolete very fast and I see no reason why this does not (or could not) hold true with crypto currencies.

Although I can see where you are going with this, it's akin to saying a scripted language or specific productivity program becoming obsolete. Despite there being many choices, the big guns have by and large stood fast (major adoption or transitions between programming languages rarely happens, and although there have got to be at least 5 alternatives to MS Office, MS Office is by and far the kingpin despite spending years between significant enhancements even during this time of swift pace).

That said, I know full well that saying this frankly more to Bitcoin than to Litecoin; and appealing to the "longevity" of Litecoin is a mummer's farce. But it is also indicative of the "trust" that more and more places are placing into a select few crypto-currencies.

Although Litecoin may be accepted by more exchanges and merchants than other alternative crypto currencies, the more innovative and valuable ones are sure to follow. Multi coin payment processing is going to become more popular as more coins come out. Having a different payment processor for every crypto currency is just not a smart way of doing things, and the ones that only accept one or two crypto currencies will be less popular with merchants over time.

This is very true; with the way technology in the crypto-currency scene has evolved, we are heading to a point where a swath of coins will be easily available for processing. The problem is the relative volatility which will either hinder user's acceptance in dealing with certain coins or with the payment processor's risk.

Yes Litecoin’s network speed dwarfs that of other Scrypt coins, and it is likely much more secure than those. However, I think it is silly to focus on only Scrypt coins.
Although it is "silly" to focus only on SHA-256 and sCrypt, they have leaps and bounds more security analysis than many of the newer coins that just pastes a bunch of other algorithms with significantly less security vetting. In either case, an invested network is harder to bring down, but it isn't impossible (after all, parts of the crypto-currency scene reminds me of the .com bubble in the early 2000's).

---

I'll be honest, your assessment on a lot of the other points are quite fair and well-reasoned. I actually see the volume of LTC actually being too high for comfort at times. And just like the BTC Association, does anyone particularly care about Litecoin's? Finally, the only plus side I see with the faster confirmation times is that it aligns with LTC's vision of being the transactor to Bitcoin's slower times; but on that point, there are a plethora of other coins that can take that place.

Nonetheless, with the investment and security built and developed in LTC, I more think it's on a medium-term decline rather than on it's death bed. Over a year and a half ago, there was a much bleaker prospectus for Litecoin with significantly less development and infrastructure; combining everything, I don't see Litecoin on it's way out. If anything, LTC grew much too fast during the November rally and things are just evening out.

The fixed hash rate idea is really interesting and it sounds good except for the fact that a botnet would easily take over the network. Often the only thing that limits botnets is the fact that most of the computers in the botnet are not very powerful. But in this case it wouldn't matter at all and sheer numbers would be the only thing that mattered.

So in order for this to work the coin would absolutely have to have full protection against a >50% attack.

Interestly enough a white paper was proposed today with a solution: http://eprint.iacr.org/2014/452.pdf
I was wondering when someone would mention PoA. I don’t see this being implemented into Bitcoin, so there is a chance for another established alt to take it up. [Frankly, I wouldn’t trust another lame “clonecoin” with this implementation, even if it did it well. It’d essentially be another piece of crapshoot hype.]

Anyhow, with the capped hash proposal, you’ve hit it on the head. A proposal like this falls prey to the PoW uniqueness problem. The “instamining” would just shift from those with power-heavy farms to those with clouds with multiple distinguishable connections (i.e. botnets).


I don't know how viable it is in reality but the only thing I can think of to guard against this problem is a a coin that integrates human intelligence tasks in order to mine. Something like a capcha but possibly stronger than that.
Yeah, it's a tricky problem to tackle. The idea of captcha-style verification is novel, but enabling it into a trustless sytem would be a significant hurdle to overcome.

Yeah, saw this on Deadspin. Nice news for Bitcoin, after all, BitPay could have called it the BitPay St. Petersburg Bowl. Glad they took the stronger route for Bitcoin in general.

Funny how, that was the main draw for the article, but the article was mostly on a BitPay and the owner's past.

I wonder how many people are actually going to get tickets for this game with bitcoin though? I can see a fair amount of overlap between sports and bitcoin (for example, gambling sites), but I wouldn't be surprised if most of the intersection don't go to games (for example, gamblers).

Enlightenment. . Tenebrix - first to implement sCrypt as protection against GPUs! Premined.

Have you been in the crypto scene since then?

As a note, there is an interesting discussion (well, more like a troll battle) that is currently going on in the Alt-Currency parent board regarding LTC and coblee (the creator or LTC) spoke to it. He actually alludes to the fact that when LTC was chosen, there were battles with parameters and algorithms (because at the time, there was a nifty little battle with deriving an FPGA and ASIC-resistant chain); sounds familiar?

Oh poor OP with literally no idea how crypto economy works.
But i have to admit that it was amusing to read.
Quote my words for future. Litecoin will hit 50 $ within a year or in worst case 2 years.
This.

Litecoin is being secured by its own ASIC hardware.

It will be the 2nd most secure coin on the planet.

I've no idea of the economy... oh my...



And SUDDENLY litecoin reaches $50.... wow an economist predicting the prices to reach off charts in 12 months.
A month ago, the same type of trend line existed for virtually every coin (with the exception to some of the "pump" coins that had only been around for a few weeks at the most). I guess at that point it wouldn't have been cognitively dissonant to assume that every coin (including BTC) was ready to die huh?

is PoS the technology used by mintcoin, too? I´m not sure what to think about.

when mint went PoS, I think, price went down to now maximum 10 sat. A coin shouldn`t be hold back in a wallet. It has to circulate to get a real value.
This is somewhat true, but then again, MINT was just a clone with a shortened PoW phase. Looking at the big picture, PPC is doing fine. It doesn't have much liquidity issues and maintains a very high market cap and strong volume; but that's because PPC has various implementations to enhance circulation. It would seem that NOBL is set up to allow for circulation. Unlike so many other coins that are just made with "features," NOBL actually has infrastructure. Hopefully though, the PoS mechanism is done within reason (no BS high stake rate, or low stake initiation periods).

On a side note, it's always so surprising that people don't know where the origins of various long-time algorithms come from. It's kinda like how everyone thinks LTC was the first sCrypt coin.

258  Bitcoin / Bitcoin Discussion / Re: Six blocks in 11 minutes! Bitcoin on steroids? on: June 12, 2014, 10:56:54 PM
Just had 6 blocks within 16 minutes (ending ~17 minutes ago)

305463    17 minutes    395    2,273.73 BTC    72.83.147.125    243.36
305462    22 minutes    32    504.36 BTC    Polmine    14.85
305461    26 minutes    81    497.38 BTC    Slush    46.14
305460    27 minutes    35    469.12 BTC    GHash.IO    21.07
305459    24 minutes    432    46,996.86 BTC    BTC Guild    287.12
305458    33 minutes    128    101,239.74 BTC    Polmine    148.88

Obviously a few fast blocks is just from random odds.


6 blocks in 10 minutes has happened a few times before, just like 0 blocks in 60 minutes happens about once a month.  6 in 10 minutes is a bit rarer though.
Since DeathandTaxes did the math for the frequency of the OPs post, I couldn't help but do the comparison of this during one of my breaks at work. Hehe.

With ideal block propagation averages:

6 blocks in 10 minutes (i.e. P[X=6] for λ=1) once every ~13.6 days.
0 blocks in 60 minutes (i.e. P[X=0] for λ=6) once every ~16.8 days.

As a note the chances of 6 or more blocks in 10 minutes (i.e. 1-P[X<6] for λ=1) is once every ~11.6 days.

So it seems that 6 blocks in 10 minutes is a bit more common than no blocks in the expected time for 6 blocks.

So it is normal over twice (or even three times) a month?
Seeing the math is amazing thank you and DeathandTaxes for doing that.
Yes, it's normal for the six block thing to happen multiple times in a month. I know, crazy huh? That's the funny thing about probabilities and proportionality. When something has a .05% chance of happening, something in a lot of people instinctively think that is super rare. But over the scale of thousands of events such as a month of which there are around 4,300 10-minute events, that .05% event has an expectancy of occurring about 2 times.

As a side note, we would expect a 7-block event once every ~3 months, an 8-block event every ~2 years, a 9-block event every ~2 decades and a 10-block event ~2 "lifetimes" (about 187 years). Mind you though, this is assuming "normal" block propagation times (which we are running faster than at the moment).

there's already a new company set to release terrahash scrypt asics in the next few months.. so we might top that 5TH sooner than you think. but if you look at how market cap works.. the reason why market cap will increase is because of the amount of new coins generated in relation to the price that it holds at in the balance between miners, dumpers and buyers. basically.. if a new coin has mined 100 coins so far.. and it's market cap is $100.. to raise the market cap to $150 all youd have to do is mine 50 more coins.. not even send them to the market or anything.. but have them register on the block chain. market cap can increase while value decreases.. but ideally we want to have both market cap rising from new coins being generated as well as investors moving up the value of each coin. we can achieve that by making sure we have demanded technolgies that attract investors as well as slowing down the amount of coins that can be generated per day.

the asics will always enjoy much larger profit margins and so the temptation to dump faster than market growth will also be much larger. effectively the asic gets to sell all of his coins before the gpu miners can. and all can mean mining out the whole block chain and keep the price suppressed below anyone elses willingness to sell. which is what i think we are seeing with noble.
Please provide me a source documenting TH/s sCrypt ASICs. I have not heard about this at all. A 1TH/s miner would be well over 3 times the magnitude greater than the Titans that KNC are scheduled to deliver during Q3. And their second batch that is slated for end of Q4 will most likely only be a ~25% hash improvement. With the geometries involved in making their Titan I can’t possibly see a sCrypt miner with 1TH/s power in the same form factor as a Titan even in the next three years. And if something like that comes out, that’ll solidify the place of sCrypt coins in the cryptocurrency world.

As for “larger profit margins” I agree and disagree. I agree that the luckiest few that get miners first will be able to enjoy significant profit parity; but as more and more people get ASICs, that parity dwindles substantially as ASIC becomes the norm. In the end, the ones who suffer are the GPU miners who refuse to get ASICs. And frankly, I’m not all too sorry for that; just like all businesses equipment and hardware has to change with each new iteration. I know some will argue for the hobbyists, but let's be honest, name me one other hobby that returns as much as coin mining for relatively little effort? People should feel lucky that they have been able to have such a handsomely rewarding hobby like this for this long. Anyhow, getting back on track. Security should be a trumping factor in the worthiness of a public ledger. As for what GPUs should move on to? The next algorithm basically. It’s a cycle that in my eyes will keep happening until there is once again too much saturation in algorithms. By then though, I don’t see 99% of the coins that exist today still being around.

The more and more I look at this, the more I see GPUs just being the gateway to determining what will be the next algorithm to secure. And maybe at the end of the road, GPUs can go back to doing what they were designed to do: rendering video and displays.

Why? I hear a lot of the people in this forum (which let's face it, is riddled by tons of FUDsters) say this, but if an ASIC is released for X11 or sCrypt-n or any of those "alternative algorithms," how would it substantively impact the sCrypt mining scene?
