I have cousins that want to learn a lot about Bitcoin so I am thinking of gifting them some not so real Bitcoin, I mean the Testnet Bitcoin but I want to know if a Bitcoin wallet exists where two people can have the wallet and start sending Bitcoin between them, which Bitcoin wallet is best for this?..
Does Bitcoin has a specific wallet for Testnet purpose only?
First of all, you are doing a really good job. But mate, I don't think so. If it is necessary to go this way, I mean, as you said, you want to guide them by sending some testnet coins so that they can understand Bitcoin. I think you should guide them about blockchain and the basic fundamental about bitcoin currency. Like, it has a fixed supply, and it is the first decentralized currency in the crypto space.
There than this if they need more in-depth knowledge, I would suggest that you bring him to this forum, as this forum is full of deep knowledge that will help him to learn more about Bitcoin currency more easily. And this is what I personally experienced: the best knowledge that I gained is from this forum, and this is why I am suggesting you do this.
