There will be another bear market, there will be a day were the market once again falls through. Be prepared and be ready. No one knows when and how it will come, but it will come. Nothing in crypto grows forever and the majority of newer-projects (<6-8months) will die out, just like the ICO boom of 2017. Tech analysis and your favorite shill will not save you, no one will but yourself and your intuition.
Definitely this! While we are enjoying the party, it is important to pay attention to all the moving parts so we can make the right decisions when the inevitable bear market hits. I generally take profits when I have good reasons to think the move is over. The market can and will eventually take the price down but you can still take a short position and ride the recovery from the drop as long as you don't sell at the bottom.
