Sorry I'm new. Who is Rpietila?
He is just a guy claiming he knows a thing or two about Bitcoin. Also owns a coin or two.
he is the guy who claims that he is a Pro trader and he can predict Bitcoin moves, the thing about bitcoin is that we can only speculate because the movements are somehow unpredictable.
when we are speculating with the charts and movements some big bag holder can just drop a shit load of coins bringing the price to the lowers lows, or another scenario is someone buying 20K coins at once and bring us to $1500 in one hour.... this what bitcoin is.... don't trade based on what we say here and don't get emotional to peoples Ideas....
Would a 20k buy bring the price to $1500?
depends where you look, If I look to bitstamps order book 20K will brings us over &1300 and looking to gox order book 20K will bring us a bit over $1100
20k spread across all markets is what you should be looking at.
if you want to bring the price up where would you buy ?
I would buy at gox, because trying to bring the price over 1300 at bitstamp will be somehow a failure, and I mean doing that by running a market order.... even if you would put some buying walls t prevent the price from droping people will simply eat the walls how ? most people will see the chance of getting their cash out of gox by selling their coins at stamp and your try will be worthless......
so I think you do not need to spread the cash, all you need is to push the price at gox and the market will follow (except china for now ...)
