Bitcoin's value has increased 18% in a week. Some experts are calling this "the return of bear".
BTC's increase in value has effect on all the altcoins.
Another major point to be noted is ETF. It is a program soon to be launched and about 10 cryptocurrencies will be a part of it.
BTC, litecoin, ripple and many other cryptos are in the list of ETF.This program will make the use of these cryptocurrencies very easy.
As the use of these 10 cryptocurrencies will be easy, hence, the whales will invest in these cryptos in bulk. REASON: the whales will invest in crypto so that their users can use the crypto easily.
EFFECT. The effect of this user-friendliness of ETF will be in the form of increase in the value of the 10 cryptos that are part of ETF.
Another effect will be that the altcoins will suffer because all the big investments will be diverted to the 10 cryptos of ETF.
