First of all....its very obvious the bull run has started. Bottom is gone since 5 weeks ago, bitcoin is steadily going up. It was obvious the night it shot to $5000 that the bull run has started, every passing week is just more and more confirmation of that. Bull run is on now (granted its only 5 week into probably a 2 year bull run so it is early days), which means next year things will actually start heating up, and we'll probably be in full on FOMO/mania/exponential explosion mode by in 2021. No reason to debate this, even if you don't believe it now, it will become more and more obvious to you with every passing day/week/month.
i think by "bullrun" he means the excited stage where there is a big in-flow of newcomers that results in a lot more on-chain transactions. and that period is mostly the final quarter of the total bullrun.
right, price is up, but volume is low. Price must maintain a 5,500-6,500 range for a few months just to be able to say the bear market is over, let alone say a new bull market has arrived
Anyway, I didn't really know what taproot does, so if it makes transactions take up less room that is very good. I guess I had read about signatures being condensed into a single one for each transaction a while back but I had forgotten what update was supposed to do that. I hope that gets implemented soon, it will certainly help somewhat.
it will be a while before these new BIPs are implemented (version 1 SegWit). the biggest improvement (IMO) is Schnorr and signature aggregation (MuSig) which will reduce the size of transactions drastically (not just 72 to 64 but from 2x72+2*33 to 64+33 for 2of3 sig) and since many transactions are multi signature these days they all can fall in size. and that is not a "small help", that is huge.
but the problem is the same as SegWit (it is SegWit version 1 after all) and that is adoption. if people don't use them, they won't be as effective as they should be.
the taproot/merkle branches update will make all scripted transactions substantially smaller, I think that's very important also.
So today, Lightning open/close tx's are ~ 20% larger than a standard 1in 2out tx. Taproot hides the unused conditions (+ sig-agg collapses 2 signatures into 1) to make them both the same size, and that's just when comparing new segwit v1 LN open/close to standard tx using segwit v1. If we instead compared to a standard tx using segwit v0 or the original encoding format, a taproot LN open/close tx is actually a few bytes smaller.
taproot also hides the fact that a script was used at all, as only the spending script is revealed (even a standard transaction is, of course, a basic spending script). So all transactions look exactly the same on chain using taproot, the only differences will be the number of inputs, number of outputs and the amounts. Most of the information is hidden, there's no such thing as a P2SH taproot address, they're identical to P2PKH addresses from the perspective of someone analysing the blockchain.
tl;dr taproot is a gigantic privacy gain as a result of it being a massive scaling improvement. Lightning on-boarding is rendered cheaper and undetectable
LN is made to be used with lots of small transactions, like everyday purchases.
it doesn't have to only be "small" transactions. it mainly has to be more than a couple. which is basically what traders do. in fact LN can reduce the risk of using exchanges by a lot. imagine you could make a deposit every time you wanted to make a trade and cash it out as soon as you were done and that whole thing didn't cost you more than 10 satoshi and it only took a couple of seconds.
right now (as a trader) if you don't want to miss an opportunity you have to leave your coins on exchanges because depositing can take nearly an hour (6 confirmation), LN can remove that. in a volatile market an hour later price can be entirely different. keeping your coins in an LN wallet is not as safe as keeping them in your cold storage but it definitely safer than keeping them on an exchange.
right, the first exchange to do this will do fantastic business. Transaction spikes happening at the same time as price spikes is nothing new, been happening since the early days. Instead, traders can have their funds ready in a channel before the spike ever happens.
Combine that with the new option to remove the per channel limit (which exchanges would really need), and the whole "micro-payments only" argument goes out the window. I can imagine exchanges using lighting exclusively; time is money when it comes to trading, so if people can move their money to exchanges in seconds instead of minutes/hours (and for orders of magnitude reduction in fees), there's no way anyone will continue to do it on-chain. Why take that risk?
i also haven't heard any exchange looking into LN.
there was at least 1 reported, but it could've been hot air. doesn't matter, it'll only take 1 exchange to do it and suddenly they'll all need a piece of the action. They'll risk being irrelevant in the marketplace if not.
