Yes, of course buying sp is the most effective thing. This is a very biased investment in the blockchain steem. Especially for steem prices now, this is the most appropriate moment. If only everyone knew how safe it was to invest in Blockchain, of course everyone would buy steem. And if everyone knows how profitable SP is on this blockchain, of course everyone will power up all of their steems.
For now, the opportunity for an account that has SP is very profitable, even if he never activates his account to make a post, because, he can sell votes for bots like @minnowbooster, @smartsteem, etc. He will get steem and fast every day. This is certainly very easy. Next, every sp holder, he will get 1 percent of the number of sp he has without doing anything. You can pay attention to accounts that have a large sp, the sp will automatically increase without doing anything.
Imagine, if you have a large SP and activate an account to make posts every day, besides being able to sell votes, you can also choose your own posts. This is really very profitable.
And you also can be able to do something to support a project to delegate your sp such as delegating sp to an account @musing.io, because @musing.io is an application that can keep the ecosystem of the blockchain stealth by continuously curating users.
Maybe this is just the answer I can answer. Hopefully you can develop it with other information. Thank you for your question. Good luck.
Buying SteemPower can have the benefit of immediate power. Having a large amount of SteemPower can give you a boost. However, this is a double edged sward. Buying Steem at a low price and powering up is ideal, but you never know when it is the lowest. If you buy Steem at a high price and then the price drops, you make a big mistake.
Leasing SteemPower can help you, just make sure you make more during the period of the lease, then the cost of the lease. Otherwise it's a waste of money, you'll end up having a deficit.
I'd say earning SteemPower is better on the long run. if you learn how to earn, you're king. Posting quality content and engaging can bring you benefits and help you grow on the long run. You won't be growing fast, but what you do is going to count later. Curation communities are looking at your results (engagement and post quality), your SteemPower is not going to count as much as the other two.
I would always buy as you then own it. being able to power up immediately and it is yours is far better. Buying at the right time is the key though and anyone doing it right now would be in a good position.
Leasing is a good option but you need to know what you are doing in order to grow. You always have timelines over your head and you never own it. I would never use this option and will always purchase and power up if I have funds.
Building up your SP is everyone's goal. having more value a s a vote will gain you more followers and will help earn more curation. I think once you own the new Steem power you will most likely make more from it than the lease period for the same amount spent. Steem is hard enough to earn so giving it away as such is not a good idea in my thought process.
Buying steempower and owning it outright is the smarter choice longterm because trust me while leasing steempower might boost your upvote value.It dissappears when your contract is terminated and that to me is not a good feeling.
It is better to invest the money you would have used renting steempower-to buy steempower.There are few exceptions where renting steempower is advisable such as decreasing resource credits and curating quality contents.Other than that i see no use for it.
