ADA is a strong coin and has a reliable history of re-testing layers of support.
anywhere in the yellow circle is safe to layer in buys, and sell at the blue line as the target.
IOST has gaps in price discovery from about 780 to 700, and from about 609 to the current price.
IOST is currently a fairly high volume coin, it has several contacts on the support at 780, with sizable bounces off of it, before bleeding out and breaking below this support.
it is a slower drop, so it is not as likely to retest this support, but a similar pattern...
