well, in this year its very impossible for ethereum to reach $2500 maybe the best price of eth in this year is about $500
but, i'm sure in the beginning of 2021 ethereum will surpass $2500 my friend
That's certainly true, mate. This is mostly because Bitcoin's price movement on the market has been relatively slow. Ethereum and other altcoins rise in price according to Bitcoin's uptrend on the market. As such, if Bitcoin rises exponentially in price at a fast rate, so will Ethereum and other coins. Now, we might still be in a bear market, but the price per ETH has increased quite steadily. I believe that once ETH surpasses the $500 mark, it'll have high prospects of increasing further until it becomes worth at least $1,000 per coin.
But, for Ethereum to become worth $2,500 many things need to happen. First, it needs to become a PoS cryptocurrency for greater scalability and energy efficiency. Then it would need to adopt the Plasma Framework at a large scale to become used by millions of people around the world. Only then, demand will rise as well as its price on the market.
Nonetheless, it may take plenty of time before we could experience new ATHs for Ethereum on the market. Just my thoughts
