Last time there were reasons which pushed Ethereum's price that high but this time I wonder what will make happen same. I fairly expect maximum $1k in case of repeating pattern of altcoin markets because this time market cap will be divided among more than one players. This doesn't mean Ethereum's importance is less but it isn't same powerful too. What is being worked on in Ethereum others are delivering before it.
Nobody expected $20k bitcoin price and around $1.4k ethereum price in last bull run and definitely history will repeat, we can expect next bull run could bigger than last one. Crypto adopted by companies and getting more famous day by day, if any big company adopt eth or btc than price could go higher and reach ATH but we can't predict that when it will happen, just invest on eth & btc.
