Also I see the last point as a complete misinformation. Bitcoin can't protect your portfolio. It can either give you immense profit or immense loss. An asset so volatile like bitcoin, can't be entrusted for capital protection. Gold or Silver can probably do the trick of saving capital but definitely not bitcoin!
1. Protect your portfolio by investing in Bitcoin
Was suppose to say the same thing when i do able to see this in number 1 list when in talks on protecting your port. I do rather see this as a more risky move to be done.
We know on how crypto can easily fucked up yet this one is more volatile and more unpredictable if we do compare it on traditional markets that we have known.
Gold would be the best choice (honestly speaking).
