What kind of returns are you expecting?

Hi,

New here.

Looking to sell goods for BTC.

I essentially want to provide a service for people to swap their BTC for goods possibly services. Removing the need to convert to fiat to do so.

Any tips on selling goods? In particular selling face to face.

I'd bring my android phone with a bitcoin wallet for them to scan a QR code. How likely is it for me to be scammed if I wait for just 1 confirmation?

You need to look at why derivatives were invented in the first place.

A classic example if farmers and their corn crop. Should a farmer grow a corn field? Given the current price of corn, it might be profitable. But it takes a while to go corn, what if the corn grows and when it needs to be sold, the price falls? He could sell the corn at a loss.

A farmer can use a derivative contract to sell the corn in say 3 months time for a set price. I.e. Contract to sell 10 bushels of corn for 50USD in 3 months time. This can reduce the risk for the farmer because he needs to make sure the capital investment now will be profitable for him in the future.

An example using Bitcoin and in particular mining which is important aspect in the bitcoin network.

Since now it is much harder to mine bitcoins and usually requires a significant capital outlay how can a person know that if splashing out on cash to buy mining hardware is worth it? As BTC gets harder to mine, more costly equipment is required to mine it.

Mining bitcoins is somewhat predictable but the price of bitcoin is less so. So a potential BTC mining operation can use derivatives to lock in a future selling price for BTC so it has more certainty that the investment in mining will pay off in the future.

Derivatives can be a useful tool but like all tools, can also be used in a destructive way. Does the potential usefulness outweigh potential misuse? That is up for debate.
