IMPORTANT UPDATE : BITCOIN FUTURE THIS IS VERY IMP

Why is it important to hold at least 60% of your portfolio value in BTC?
A very important topic about BTC Because this is very important.FIRST BTC is the lead currency.
Without Bitcoin there would have been no Altcoins, and if Bitcoin dies all Altcoins will die with it.

Bitcoin is the most valuable digital asset and for a good reason.Bitcoin is the only truly decentralized and leaderless cryptocurrency in existence.There is no man to arrest and no company to close, it cannot be stopped. Second, it is the most secure cryptocurrency out there.

Nothing matches with the hash power that is used to secure the network. People often make the mistake to think that BTC is wasting energy or polluting the environment. This is not true. The energy in PoW is consumed to anchor the Bitcoin blockchain into the real world, because a real life asset (energy) is consumed to secure it. Satoshi's design is architected that every miner must use a scarce asset and consume it to prove that he has made a financial effort to participate. This scarce resource is computing power, fueled by energy.

Another common mistake is to think that Bitcoin is slow and not contemporary. This couldn't be further from the truth. It is right that other, smaller projects integrate innovations like SegWit or atomic swaps faster, but not because they are advanced. It is because with BTC stability and security are above else, they test everything a hundred times before implementing. and BTC will likely inhabitate most of the features of Altcoins in Layer2 solutions. Fast payments are coming with the Lightning Network, smart contracts with Rootstock, side chains with Drivechains, privacy with MimbleWimble and Schnorr signatures.

Another important factor is institutional money, do you think they will invest in DApps or tokens? no, they won't. They will buy either a scarce store of value (BTC) or cashflow generating (through PoS) platforms like ETH or Cardano. They will buy the fat protocols, not the light applications. So, many people are all-in in Altcoins.
Institutional guys will buy BTC and ETH. And you should always take profits and stock BTC up. If you don't then you will get rekt when they bubble bursts and you hold hundreds of thousands of Pets.com because you loved fast gains more then buying Amazon stocks. Yes, altcoins can gain faster but this doesn't benefit you if you don't take profits and end up with dead tokens.
Please think about what I am saying. Thank you
