There is no such thing as gavincoin and mpcoin. (false info) OP is part of a co-ordinated smear campaign. (false info)

The strategy of OP is not to 'win' any argument about which coin is better - its as a trick to make you accept that there exists 2 coins automatically by arguing for one of them. (i don't even understand what he is saying here)

There is only one coin, Bitcoin. (two after the fork, well, Gavincoin and Bitcoin) There will be an update of the software, it will be well telegraphed, everyone (not everyone) will upgrade in plenty of time. Once the date passes then miners will be able to create bigger blocks when they need to, once that happens then people who haven't bothered to upgrade will suffer. (remains to be seen) They will be forced to upgrade because otherwise they will not be able to mine anymore. (false info, mining on the original bitcoin chain continues normal)

There will be no drama when this happens. There is no 'other' coin. (again, he just ignores it like he ignored the price all year) There is no debate. (so what are we having here?) The OP is just trying to drum up interest for their boss MP (i don't even know who MP is besides that i was reading his website) who's argument is that changing the block size is heresy, despite satoshi himself having said that this change can be phased in exactly how it is going to be (satoshi didn't say what gavin thinks he said - has been pointed out in the thread already)

He well understood the network needed to scale http://www.mail-archive.com/cryptography@metzdowd.com/msg09964.html

The only people that really have a problem with this (aside from the short interested bears simply glomming onto it as a way to talk dow the price) are those that fail to understand the most simple math.

1MB blocks mean a maximum of ~4000 transactions * 0.0001 transaction fee = 0.4 BTC max potential fees for a mined block
20MB blocks mean a maximum of ~80000 transaction * 0.0001 transaction fee = 8 BTC max potential fees for a mined block

Gavin's proposal isn't lets go to 20mb blocks and leave it at that though, it's lets scale max block size over time

(The blocks on gavinfork will be filled in no time with all kinds of shit - 20 MB will be there in no time and 20MB is just the beginning later it will be much more)

If you think limiting the block size will make people pay for transactions you are ignoring i) the most basic principals of human nature ii) sidechains, alts and the million other ways that people can transact of chain to avoid paying higher fees. (it is inevitable more chains will exist and actually it is more practical and more rational)

What it also fails to acknowledge is that one of the big argument for bitcoin is "no/low fees". How is that going to remain the case if now we are saying that actually you have to pay fees to get your transaction in the next block. It just doeasn't make any sense. (thenetwork won't be able to operate without fees after the inflation fades off in a few years - the blocklimit is an important metric to keep the chain viable. Nobody says it shouldn't be raised but it shouldn't be raised ahead of the demand because no fees will not work later because miners won't mine - the end of the story will be quantitative easing more coins into existance on the Gavincoin fork later)

The *only* way for fees to take over from the block reward as the main source of revenue is by increasing the volume of transactions such that tiny fees per transaction add up to something worthwhile. (the volume of transactions won't increase on a coin scaled up ahead of demand because nobody can afford to download 2.8GB ever day)

Its really simple maths.

Don't let people distract you from the simple maths with their imaginary drama.
