There are allot of places where you can invest your coins but i dont think you have enough with just one coin to invest. Maybe on a long run it wil be profitable of you invest in the right one but just one is not enough..
Indeed there are all kind of startups where you can invest the bitcoin as an example you can invest in start up company's.
Just remember that there are so many kinds of investment sites where you can invest. But if you want to go mining, you better invest your money
into hardware and buy some hardware that you can use for your mining rig.
But I think still 1 btc isn't enough to have a good mining rig.
Mining isn't that profitable nowadays. Be it online or be it in a hardware. Having a 1BTC mining rig isn't that bad for a mining rig. The difficulty is the problem. If you were to mine in the previous years, it might be profitable. But now, most people don't suggest mining unless you have a really good mining rig.
Mining online is an absolute scam. They are just ponzi sites where they pay you using the money of the previous investors. Pretty sure most of you are well aware of this so I don't have to explain much further.
Absolutely right mining rigs are not profitable now since blocks is more difficult to mine now thats why miners nowadays dump or sell their rigs because they find it not worthy nowadays and even cloudmining site are sucks theyre just made just to scam people and stole their hard earned money but theres site i can recommend to mine like eobot where you can rent their pool and mine eth,
-I dont recommend "poinzi" etc. You can lose your money like gambling!
