1) Where are you located? (i.e. from which country do you dispatch your products) I couldn't find that info on your site. Since there might occur import taxes (depending on your location & the dispatching locations) I believe that this info should be mentioned somewhere
2) "each DigiPiglet will contain approximately €10 worth of Bitcoin as a starting credit." Are you going to use the bitcoin market value at the time of placing the order (for calculating those €10 into BTC), or at some time later on when you will be ready for dispatching (this info should be crystal clearl & available on your site FAQ)
3) Your idea is not 100% original. There are other companies with similar piggy bank products. What are the strengths of your product compared to what is currently available on the market?
Concerning the private key security issue: one of your competitor does the following: Displays the public address QR code directly to the plastic piggy on open view. Everyone can send BTC to that addy (hence it acts like a piggybank). When you would like to withdraw (i.e. break the piggybank in the traditional way, and collect the funds): the piggy comes with an opendime attached (and the public QR code addy derives from that opendime private key). Hence you break the opendime (instead of the piggy) and the private key is revealed. No private key trust issues here. Also (for more privacy) gives options for the customers to print the QR code itself and place it to the piggy (either from the included opendime or from any other opendime)
I do not want to mention the name of that company here (it would be unethical to do so on your topic, due to competition). I would gladly let you know through PM, however (for research purposes LOL).
1) We will be selling from Austria. You can buy Bitcoin in corner stores there. Legal pages for the website are in the works.
2) We'll set up a system, where the Bitcoin are purchased automatically with each sale. For now however, while we're in early stage, we'll buy Bitcoin manually to have it ready once the labels arrive. If the price happens to drop by the time we're ready to ship, we'll just make another market buy and hold the more expensive coins. I think it's quite possible that prices drop to 3k again. We'll make sure that this does not tarnish the user experience. Once the price starts becoming
really volatile again though, we won't be able to guarantee that the 10€ will not turn into 5€ or 15€ while the piglets are being shipped over night. That's your typical crypto risk
3) I think I know which project you are referring to, they have a different execution, different features, different advantages and disadvantages. Our design is unique, which makes it stand out more. The underlying "technology" we're using is very simple and requires no setup, no prior knowledge, no computer, literally nothing. Many other projects I've seen are geared towards people that know what they're doing and dealing with. Our goal is to win over those who doubt us, distrust us and don't see the value in it, and therefore don't want to learn anything about it. It's designed to be as simple as possible, requiring literally no steps if you just want to hold on and see where it goes. At the same time it's somewhat familiar, because we are and look like a piggy bank. By adding different models/animals, we increase the novelty character and it becomes a collectible.
They are designed to be a little squishy, so it can get quite addicting to play around with it
