Currency selection formula: BTC → ALT → ALT TOP 5 → BTC

If you don’t know which asset to trade, choose BTC first.

If you think BTC’s volatility is too small, then trade altcoins.

If the volatility of altcoins is not large enough, then choose the leader among altcoins.

If the leader of altcoins rises too much, returning to BTC may be a more stable choice.
