4. lastly Buying Altcoins are not diversification means so do not take profit from bitcoin to buy Altcoins.
Why not? Example on XRP, if you have it even just october last year or on the last 9 months, you are now 5x or 6x richer, compare if you have bitcoin in the same month, you earn x2 as well. Having ALTs doesn't mean you are abandoning or betraying bitcoin, its diversification.
If you have both coins last year or the month mentioned, it means you have at at least x8 profit instead of x2 only.
