All things about cryptocurrency are very new to me; however, the more I learn the more exciting it is and the more possibilities I see as an application developer. I'm particularly happy to have made progress understanding smart contracts. Not so happy with learning how to move tokens from one account to another or exchange for different types of tokens. Apparently, one can do this in not so efficient ways and lose or perhaps spend a lot on the transactions. Anyhow, I think I've got a better understanding of that now as well and have been reading about micro-transactions and future plans. While doing so, a new issue became clear. Privacy.
Before I can see family, friends, and businesses widely accepting cryptocurrencies for exchanges, ones I know will want very low transaction costs and very, very good privacy. For example, I don't want my friends knowing that I'm paying a particular doctor, much less having every convenient store gaining access to the same. I don't want strangers knowing how much money I have. Within a day or so of experience, I haven't learned how to maintain privacy and have learned how to see everyone's transactions. How can a person maintain privacy? How can a person regain privacy after entering the ecosystem?
