Now it cannot be said that a pool can be safe because all pools are very centralized. This means that the founder of the pool can steal your money.
That's right I wanted to stake some of altcoin but am afraid that I might lose control of my coin to the pos because I have to rely on them to make the staking capable wallet and send me my log in details. I will rather wait till I get the right equipment to stake on my own rather then relying on a poll to do the staking on my behalf.
