Often times yes!
Not only as a wallet but like an investment for the future. I am proud to say this that for the past 8 months that I have been on this platform, I haven't invested any real money yet on Steem. Whatever rewards I get, I use most of it to power up into my account. So far I already have 750 SP on my account without investing anything.
And I am not planning on powering anytime soon. For some this might only be a small amount but I see it as a slow investment for the future. With how hype SMT's are and how revolutionizing the blockchain technology is, I really do think that this small wallet of mine will start to make a difference years from now.
