If anyone is looking for the next doge, you should invest and buy every token that launch in the market. Spend few $$ on each, who know's it might worth something in the future. But expect some losses along the way.
It is only applicable for a huge fund to take that big risk and it would take long before you know the next Doge when every token that launch is going to invest in. For me i would rather to prepare for the potential altcoins that are on the top 10 of the coinmarketcap like ADA, ETH and BNB.
