Polkadot, Cardano, ETH and Blocknet... All projects with huge news, huge moves, and huge increases by August this year.
It's the year of the Dapps and the DeFi now if you are investors and you are not investing in this kind of project you are losing potential profits, all the coins you've mentioned and similar coins that are making a name in the community will be the coins/tokens that will take over the industry in the future, and will soon become a threat to existing popular and hype coins now like Doge, Tron and Litecoin.
That depends on how long the bulls will stay.
The market is pretty much hype now, don't expect that the bull run stays a year long, it has not happened in the past year, altcoins season is also short, so take this opportunity now to invest but of course with caution. These coins that are mentioned may have a good future potential, but I'm sure they will go through heavy correction first before they will reach their ultimate success.
