I always tell people to put as much as they can into BTC because all other coins depend on it.
There are coins that depend more like forks of bitcoin and ones that depend less like IEOs but in the end it all comes down to if bitcoin is in a bull or bear market. If it's in bear everything else is going to be, so why would you get 100 different coins with different protocols, wallets, dev teams when you can have one and more or less have the same profit?
You can set aside 5% for small caps. 80% of altcoins are likely to pump at least 2X on this bullrun so that's something you can consider. The risk is higher but your portfolio will not be affected too much if the gamble loses.
...You could increase you BTC at the cost of LTC.
70% BTC
30% LTC
30% ETH
This is 130%
He made so much profit that he lost count
OMG
That is a great interpretation! If I were you, I would allocate X 50%, Y also 50%, Z ALL IN 100%. You know what? Also give 70% to A! Hilarious how he obviously didn't realize with his three numbers that it doesn't add up. BUT - we all make mistakes!
