Right now with any crypto, unless the price is locked in, volatility in real world fiat price could outweigh the reduction/free in fees.

HIVE, even though there is no direct transaction fee, liquidity is a challenge for large amounts for it to be feasible.

For large transfers, BTC fee is a tiny % compared to the legacy banking system. For smaller transfers, fees for ADA, BCH, XMR for example are low enough and have better liquidity.

HIVE right now feels like an excellent solution in the micro-transaction space and needs to grow up before taking on bigger ticket items.
