I would probably put a huge bid wall up at $5/BTC and as people buy, sell at $5.50 for at least a year to give some price stability in the early stage.
With an estimated market cap of $44M (8M BTC X $5.50), 1M users would own on average $44 worth of Bitcoin.
And getting those 1 Million users would not be that difficult, if:
100 current users got one new user within the next week, then: ~ Only need to get 13 new users total.
200 users (first 100 and next 100) did the same the following week, then: ~ Only need to get 12 new users total.
400 ~ Only need to get 11 new users total.
800 ~ Only need to get 10 new users total.
1,600 ~ Only need to get 9 new users total.
3,200 ~ Only need to get 8 new users total.
6,400 ~ Only need to get 7 new users total.
12,800 ~ Only need to get 6 new users total.
25,600 ~ Only need to get 5 new users total.
51,200 ~ Only need to get 4 new users total.
102,400 ~ Only need to get 3 new users total.
204,800 ~ Only need to get 2 new users total.
409,600 ~ Only need to get 1 new users total.
819,200 end game!
But, it won't happen if the average maximum is only $44 USD in your pocket.
But, would the first 100 do it for at least $1,000 profit? As well as the same profit for the second group? Third? And mostly likely the last group on my list above?
Now, I'm not taking Ponzi, or pyramid, or MLM here.
Want to hear more? Send me 10 BTC and... Only kidding! In fact, I don't want anything. This would cost nothing to do (as far as paying for a service or product is concerned). Let me know if your interested, and I'll outline how. Of course there's still the rub: ease of transfering BTC and merchants--chicken/egg dilemma.
