None for $8.00 / BTC. But if it dropped to something ridiculous like $1.00 / BTC or lower I would probably buy as many as possible to sit on.
I'm pretty sure that >90% of the people that say stuff like: "if it dropped to $1 I'd buy shitloads" would not even read the forum any more should that happen. Plus: They would've shouted: "Oh my god, Bitcoin is dead because of
" all the way down.
Bitcoin will appear dead - it may even actually be dead until the next cycle. The problem here is that there may not be a next cycle. This is just part of the affect of an unregulated system - cycles. There is no one here that will defend BTC, ie act as a buyer of last resort. This is a pure market function. Price stability plays no role in pure capitalism.
Most folks would rather have a stable currency rather than one that swings for the fences. For Bitcoin to grow beyond it's current purpose and stop being a vehicle for speculation, it needs to be a virtual currency that can store value over the long term. This depends on uptake by common folk - not crusaders, not criminals, not technical gurus. Otherwise, it's only economic contribution will continue to be a way to transmit value for folks who don't like traditional transfers or can't use traditional transfers - which is a very niche market - realistically this is a no or little growth area. In other words, common folk will only hold it for a short-time, days, ie buy some BTC, trade BTC for goods or services, but never store it for the fear of loosing value. In that case, it will continue to swing due to un-smoothed demand and availability. The growth of available BTC is a fix daily amount if we disregard BTC traders/speculators - BTC is not elastic. There is no entity that can add or absorb liquidity to stabilize the value of BTC. If common folk believe that BTC is a stable store of value, they will hold it.
As for the original question, none at 8. It's an imperfect question. Really this question fundamentally assumes that it will go above 8 again, that may not be true. Personally I believe, it has much further to fall than 8, and once it falls thru 6.1, it may not see 5.8 until the next cycle. If I was seriously concerned about people losing money, I would advise folks to do a technical analysis and look at the chart and figure out the most likely support/resistance level...which to me means around 6.1-5.8 (it's a moving target). However, that doesn't mean it won't move lower, so I would further advise folks to keep a reserve in order to double down at the next resistance level. But I would also be wary of external affects, such changes to MtGox. Or the declaration by the US or UK that bitcoin is persona non grata.
I believe that BTC/USD is in a super down trend right now, and all technical indicators will be late indicators.
