I think the situation is simpler than it seems. Crypto spreads are adequate, but their current volatility leaves much to be desired, so it seems that spreads don't let you have a profitbale trading. It's not true. Look closer, bitcoin has been under consolidation for 6 months. The crisis is right around the corner, just like ten years ago, so investors don't rush to invest in high-risk assets, and the volatility of hyping currencies is at the minimum. The further away, the more valued the traditional safe-haven assets become, same for gold and bonds. With confirmed bullish sentiment you can profit on everything else, it's good that spreads allow you to do this. That's what should be in the limelight
