I received a vouch copy from the op and here is my personal and honest review.
The method involves an arbitrage, a process of buying something cheaper at point and selling it higher at another.
The op included where the materials can be bought and sold however the source of the seller to acquire this material should be verified to be legit before transacting with them.
thanks for your review i want to ask you question that i should buy electronic goods or i should buy real things?
another question that is this method is worldwide or only work for a few country?
electronic goods, and its not working worldwide as I checked
if your country isn't supported you are getting a refund
