now Bitcoin price has increased 17.5% in the last 7 days and now the price is $27,750.69, then BTC Domination is 70.9% with Market Cap amount $727,677,130,354, but Ethereum price is currently $644.61 and is down 1.44% from the last 7 days, so I bought Ethereum with all my money (money that I use specifically for investment), because I believe Ethereum price will soon increase very high (bull run) following Bitcoin price movement and of course I will get a very big profit from investing in Ethereum (my target for Ethereum price is $1100-$1400), because I believe if Bitcoin dominance decreases, then it will make the price of altcoin increases (including the price of Ethereum).
do you still hold Ethereum to this day or have you sold it at ATH in april?, when the OP made this post really irrelevant for now. "Are you really sorry for your decision or are you proud of your decision?"
If you haven't sold it by now, the value of your investment has tripled, you bought around $600 while the current price of ethereum is around $1800, this is very profitable and exciting.
