I'm new to cryptocurrencies and I would like to know, is there any possible legal issues with cryptocurrencies? I'll appreciate your valuable ideas and please help me.
That would depend on where you live. Since this section is only for Bitcoin discussions I will focus only on Bitcoin.
If you live in any of the following countries you should be careful with using Bitcoin as it is illegal.
Ecuador, Bolivia, Algeria, Morocco, Bangladesh, Nepal, Vietnam.
In the below countries it is not illegal but it is either restricted or non regulated.
China, Egypt, Mexico, Saudi Arabia, Russia
You can read more about this from the below sources:

wikipedia link is quite well updated and is a good reference link, but I would always advise that you ask your local authorities first before doing anything. In general, these are the tax authorities and the business authorities. The former you always need to clarify with when filing taxes, the latter only if you're doing business with Bitcoin. In my experience, your local (municipal or city) supercedes anything, even if legally it is national law that does, and if you get clearance from your direct authority, it all works out.
Also, Saudi just this week recognised all crypto as securities - so definitely not non-regulated anymore.
