The problem with doing research to find the good projects, is that being a good project doesn't necessarily equate to making good gains. There are two altcoins which come to mind which have been launched over the last couple of years which I have vaguely been paying attention to. These projects went on to develop an actual product, move from tokens to their own blockchain, set up business partnerships, etc., which is a lot more than can be said for 99% of altcoins. In terms of price, they have both been slowly losing value in the bear market, and have lost even more now that BTC has taken off again. Compare that to utter scam coins like EOS or Tron, which have been gaining value of late.
