No. I was talking about the people, not the use.

In Argentina we have the top development team of BitPay, developing cutting edge stuff like Copay, Bitcore Wallet Service, etc. People like Matias Alejo Garcia, and Manuel Araoz (now a BitPay alumni). Look at: https://github.com/bitpay/bitcore-wallet-service and other projects.

We have Sergio Lerner, one of the top security researchers and the official Bitcoin Core security reviewer. Look at his blog: https://bitslog.wordpress.com/

We have also projects like Xapo.

And many many others like https://streamium.io/

Not mainstream by any stretch of the imagination, but we still have the strongest Bitcoin userbase in the region, with Brazil in close second.
