I learned about delegation few years back. At that time STEEM delegation was very much popular among the content writers. After few more years I learned about the ATOM delegation aka staking for which good amount of rewards are given. I also recently got myself into the Hive delegation too. I hope you have seen my article on the hive delegation which covers the Hive accounts worth delegating to, read here.
Now coming to the crypto investment, I feel like delegation and the proof of stake blockchain are two options which are going to open up new doors for the reward earning. Some may offer the rewards on daily basis and some may offer it in 90, 180 days basis. It all comes down to what you choose as a time period for your delegation or staking.
I have staked my Hive to the accounts which offer some decent rewards - indiaunited and hodlcommunity. I wish to invest into few other accounts which include leo.voter and few others. But I am not aware of the minimum amount which is good enough for delegation.
My current Hive delegation looks like this.

My next target with the Leo community is having the 1000 Leo Power and maybe I could get into the zone of the Leo delegation too. Which would make it easier for me to earn the passive Leo rewards from the delegation.

I also feel like investing into the community using the stakes as it can be rewarding for the both parties. Like you delegate your tokens power and then you earn the token in return. I feel Hive will have around 1 to 2 USD worth of value in near future. So investing into the hive power would be a good deal in the process.
Future Delegation Plans?
My plan is to do the same with Ethereum and have it in staking. It may take a year more from this point onwards but you never know how that would go. I have some expenses to make. I have to think of retirement and the income for the everyday expenses too. So overall I suppose that would add up in the grand scheme of things too.
I like investing into the assets that can give some of such returns in the form of delegation. It'd be a good thing for both crypto and investors to have cash in circulation like this.
What are your plans for delegating any crypto? Any favorites?
