Plus i have some cash in my PM account and I really don't know what to do with them, I mean is trading a good choice? Shall i wait till bitcoin price falls a little bit to buy and then wait till the price gets high to sell?
Like I said Crytocurrencies are highly volitille, I do trading myself, and I haven't made much of a profit during last 12 months, infact I lost 50 % of money invested in buying, now things are stable since bitcoin is back up again, but what will happen in a week or a month, or even a year, none can tell, for all we know bitcoin my collapse all the way to 0 tomorrow, but than again it may rise up to a level it wasn't ever before.
I won't tell you what to do with your money, only you can bring that decision, if you trust and hope that bitcoin will one day rise up by 200-300 %, than by all means go ahead, but as stated before the risk of loosing money is equal to the probabillity of earning money, and if you do earn something, there is likelly sort of tax rate you need to pay to your guverment, wether or not is this worthwille to you, decide for yourself.
And what do you think about mining?
It depands what cryptocurrency you want to mine, and how big your buget is.
What I meant by buget is that you need a special computer configuration in order to be able to mine (multi-GPU configuration).
These are quite expensive to build, also once you build them, there is a certain running cost (power bills, enviromental cooling, space, etc., also there is a mantanance factor should any of your hardware fail, and that is likelly because your GPUs will be under constant 100 % load - something they were not designed to do.), These are for mining altcoins, if you want to mine bitcoin than you need a special ASIC machine (also expensive, and hard to find), since mining difficulty is too high for any computer to handle.
Latelly mining isn't really profitable, mining difficulty is quite high, prices have fallen quite a bit, also electricity bills are getting more and more expensive, thus mining is less profitable by the day.
Do your math:
Can you afford an ASIC machine/multi GPU mining configuration?
If so, calculate how much power will this configuration consume.
You need to maintain enviroment temperatore as cold as possible (while mining your configuration will produce a lot of heat), so you will need some air conditioning, how much power will they consume?
In an event of hardware faillure, can you afford the expenses?
Now calculate the profit using some sort of online mining calculators like this one:

Now see for yourself whether or not is mining worth the truble.
One more thing: little warning about cloud minning services: Those are also a frequent way of scaming people, your best is to stay away from them as well.
Once again I will repeat a sentence from earlier in this post:
It is your money, do with it as you see fit, I will not tell you to spend it or to save it, the only thing I can, and I did tell you is some advice, don't rush things and do your research.
Best of luck, you will need it.
Best Regards
