From my experience in Steemit and trying various robots, upvote robots, delegates, vote selling, and various other investments such as Steem Monster, etc., I can deduce the best strategy for your investment.
Note: I am not promoting any services, just trying to give tips.
The Best Way
- Delegate to @ steem-ua, so you can get at least 40% return from your delegation in short time. But you need to be active, at least post one qualify post per day. Oh yes, you need to make sure your UA (User Authority) score is becoming bigger to get more upvote.
- SmartSteem
There are 2 options here, namely:
Delegation - passive income, but no curation reward.
Vote Selling - you can use your SP as freely as possible, get curation rewards - but your UA will drop.
So, choose and consider Smartsteem according to your activities in the STEEM network.
And, make sure you leave 30% of your SP to follow various other famous dApps because it will make you ride faster.
