I saw an staking today and the project called Elrond, Their staking has have 10 wave or phase of staking and now was on wave 2, the total supply was 17,000,000,000 ERD and only circulating was 6.612B each wave will be end if they reach the maximum 500M capacity. And the price still down fall, What is your opinion if they reached until the wave 10 and its almost all of circulating supply will be locked for a minimum 30 days up to 1 year.
I too had a look at Elrond and it looks promising. But as you said, they might not be worth the hassle if you could still buy them cheaper at a later time.
I have a few coins that are staked, NEO, Tron and Algorand to name them. I rather focus on the high ranked coins by marketcap as they have lower chances to fail as many hedges use them on their portfolio.
