Let's be realistic here, the market for ADA is quite extended right now so expect a pullback then a bounce off to the upside. This is looking very bullish especially with the smart contract on the side so expect to break the all-time high.
The RSI is above 80 so look out for the prices to either stay stable or correct itself to around the $1.9 level. I still believe that after this correction (I may be wrong), the prices will likely go parabolic as it has proven before.
A good opportunity to buy right now would be patient for a pullback to 1.8-1.9 or a market crash (anything can happen in crypto as we've seen it before). You could indeed short right now but add a stop loss at about $2.2 because we've seen how bullish ADA has been in the past week. You may hate me to say short right now you have to sometimes be a bear and sometimes a bull to be a good trader.
Good Luck EVERYONE and don't trade money you can't afford to lose!
