There's no other promising coins on the space bro except of the top altcoins in the market , coz they are legitimate than what others recommendations in the space, for example a new projects which is clearly very unpredictable.
So you better to stay away to it and choose a project where you can really get good return than trying a new projects that you don't even know if you can get from it after all or not. Be smart and be wise to prevent trash coins.
New projects can also be promising, you just need to understand how it works and analyze the project. Though it’s more risky to invest on new projects simply because they don’t have a track record yet but still if you are ready to take the risk then I believe it can be more worth it. Top coins are already given, this is your safest option to stay alive and active on this market but of course you can’t stay with them forever so better to learn how to spot a new good project, you might get lucky finding a good gem.
There's no doubt on this, some new projects are able to land on the top spot because they have a good community and a good technology as well so don't close your mind to new project, just wait patiently to see another new good project, you can still be lucky for that. If you are tired on looking for that good project, then that is the time for you to buy the top coins, they are good and better if you diversified your money as well.
