RE: Bank of Spain Warns Risk of Extended Use of Unregulated Cryptocurrencies

Using much secondary cryptos can defintely provide an unnecessary risk in terms of safety AND volatility.
Using major cryptos gives more stability in terms of IT-safety, less volatility and a wider community ready to help.
But this thought, is still good even for fiat currencies, since many secondary fiat currencies are much volatile, not widely accepted and can create suspicions into providers.
