I think that's the best way to go about buying. Not necessarily waiting on an unpredefined dip to become so pronounced but, to buy where you asthenia investor feels is best for you or to be dip enough. While, keeping some money to reinvest should further opportunities crawl out of the market by making further dips. Just waiting and waiting could lead to procrastination and so, you've just got to go with your guts.
A 50% banked cash, its a good one too. In times like this, new money into the market makes a lot of difference. Some swap between coins and feel they are investing and making a difference.  Well, it might be if the coin does more multiples than the formal else, it makes no difference. When it comes to introducing new funds into the market and you've bought a good coin, it makes a whole lot of difference.
