Because bitcoin is the benchmark of all the cryto money. if the bitcoin price drops all altcoin prices are down if viewed from the price to real ang or dollar, but the decline in bitcoin prices may not necessarily affect the price of altcoin in exchange for bitcoin.
Maybe this is one of the reasons.

I do not think bitcoin prices can be manipulated because bitcoin prices are set depending on market demand. The decline in the bitcoin price was fueled by investor concerns over regulatory upgrading in India and potential price manipulation in some major exchanges.

Why do I need bitcoin. Because Bitcoin transaction process is generally much faster. Bitcoin transactions can happen instantaneously if the transaction has a "zero-confirmation", which means the trader takes the risk of receiving unconfirmed transactions by blockchain, a kind of Bitcoin transaction confirmation technology. Alternatively, they can hold about ten minutes if a merchant needs a Bitcoin transaction to be confirmed. However, the process of bitcoin transactions is still much faster than inter-bank check transfers.

Is it possible facebook and other companies hijack the blockchain movement.
I think it can happen. if the implementation of cryptocurrency by Facebook becomes a reality, it will encourage the use of digital currency massively in the wider community.
"With more than two billion active users each month, practically, Facebook can control the world community in adopting new things,"
how Facebook looks for loopholes in implementing decentralized peer to peer cryptocurrency transactions.

Bitcoin is an electronic money made in 2009 by Satoshi Nakamoto. The name is also associated with the open source software that he designed, and also uses a peer-to-peer network without centralized storage or a single administrator where the US Treasury calls the bitcoins of a decentralized currency. Unlike most common currencies, bitcoin does not depend on trusting major publishers. Bitcoin uses a database that is distributed and spreads to the nodes of a P2P network to a transaction journal, and uses cryptography to provide basic security functions, such as ensuring that bitcoins can only be spent by people owning them, and never be done more from one time.
Hope this helps.

I think bitcoin can not be used for the whole world, because Bitcoin around the world is almost reaching its limit. To date, there are already 16.8 million Bitcoin successfully mined by miners. The depleted digital currency stocks are running low. Because it is only 20% of the total 21 million Bitcoin pegged by Satoshi Nakamato, the creator.

What I know, the blockchain's smartphone is that it offers better security and improved user experience by integrating the storage wallet directly into the device, and enables direct trade of the original cryptocurrency without the cost of mining.

This is my opinion.

Altcoin growth and development in recent times experienced a very significant increase and increase.This also affect the investors to compete to invest in projects on the altcoin.

Bitcoin Cash will be split. The fourth largest Cryptocurrency, itself "branched off" from Bitcoin since August 2017, is scheduled for a "hard fork" on May 15.
