Just spam.
Ignore it and do not advertize their sites.
Do you post a new topic each time when you receive spam emails or junk mails irl?
I've never received unexpected deposits before.
So you're stating that this is a means of spamming, hoping I'll visit their site?
The first name BTC SmartInvest I found no url. The other btcsmart.net there were many urls in different countries.
So you're saying this is normal?
How did they obtain my wallet address - by studying the blockchain and recording every wallet address they come across?
This is all new to me (not btc but receiving "spamming deposits", if that's what this is).
It made me paranoid and wondering if I had some sort of security risk, which is apparently not the case based on your post.
"Just spam.

I would advise all reading this not to go the website. I'm not going to.
