Ethereum, of course, should grow in price by the end of the year, taking into account the successful implementation of Ethereum 2.0 improvements and given the common reasons for the growth of the cryptocurrency market. Will such a price increase be five-fold - we'll see.
Coin BNB already has a rather high price. It can rise in price, however I do not think that five times.
I haven’t heard anything about Polis. Yes, most likely, this topic was created to advertise this altcoin.
