For this method to work, u will need a minimum of $250 BTC investment.
Yes its not 100% safe.
Works best if you have a US address.
It will take longer time if you are not from US.
If u are not from US then u will need to prepare more than $250 of investment.
OP needs to give these details as these are very important to those who wanted to buy.
There are some more things that u need to prepare so the initial investment will be more than $250.
Take note.

OP has a good guide. I actually use this method already, but it also gave me a few more options I could use. This is working I can tell you that.

OK, sending PM now.

@ worhiper after reading the vouch copy are you really saying that $25 is a fair price for this product? Is this legal?

Got the vouch copy. OP's method is using existing and public resources but he's put it together in a way that it'll be useful even to people that knew of those prior because it uses features that aren't very well known. I find it time consuming and also risk bearing but rewarding if done correctly. The method does require significant amounts start with initially and some work too to make profit. I think this guide is good for people that own some bitcoin and are looking forward on using it to make money but aren't very familiar with bitcoin-related services, that's because it uses resources publicly available as I said earlier. The price and the requirement don't really make it ideal for people without many funds to begin with though.

That's my review. Overall I can say that OP didn't make any overstatements but be aware that there's still some risk.

I'd take a vouch copy for a honest and detailed review, please let me know through a pm if you want.
