Made a quick and simple look over the altcoins, selected the best ones and pretty much similar setups for them all. A classical retest of the breakout area and some other criteria to add strength to the breakout/retest area.
Obviously, it all depends on the BTC price so let's consider these buying areas as a long-term investment because technically they are pretty good to invest into your favorite coin from the current prices.
Every picture has a green box, it marks the buying range which allows to buy it from the good price of a technical perspective. If the price falls lower than the lower line of the box then you should be cautious!
Hopefully, you find something:
