If you are looking to invest then i would advice you to bet your chances on the first 20 cryptocurrencies because those coins seems pretty sure to rise and fall at some point in time so you can earn some profit in the future. But above all please invest an amount you can afford to lose so that if crypto should die at any point in time you would not be dependent on people.
Good advice, now almost all the coins from the top 20 look good, the prices are small and even a small jump of the market will make it possible to earn a decent, the more there are coins that cost less than $1
