When everyone is too optmistic about something, I usually afraid and cautious
Everyone is expecting BTC to hit and pass ATH, but I'm feeling that the scenario will be different, if BTC don't hit high prices, people will be disappointed and start to sell, this is my opinion
Either way is a good opportunity. Although its hard to resist not to be worried but is it good when the price starts to rally upward and it's also good to buy when people starts to dump because the price will decrease. Its really hard to control your emotion while watching the market rise and fall.
