I'm currently considering making a investment that requires bitcoin as payment of around 15K and looking for any advice.
I've tried searching search engines with no success.
Anyone know if there are smart contracts or any type of receipt or anything else I should request or anything else to cover my investment?
Or, no luck and it's a big risk.
Any advice would be much appreciated
Bitcoin is lacking smart contracts, which means you can't force the other side to make payment or deliver the service. Once you send money it's over for you, you can only wait for them to fulfil their part of the deal. Did you consider escrow? You send money to a trusted third party, accepted by the contractor, that will keep it safe until your the contractor delivers. You could also agree to divide the money into a number of smaller payments released over time.
I agree that if you're sending first without any escrow or collateral the risk is big.
