He is crazy, and obviously that he is a newbie, no one can trust him. Why would someone who is not crazy of have a mental illness would invest in a coin like bitcoin gold? No one, so better to do not pay attention to this
My advice:
Shortterm: BTCgold
If you are really going to hold it, and you know that you are never going to feel tempted to withdraw that money, then follow those advices.
Buy bitcoin with at least 70% of your total funds, if you have one thousand dollars, then invest 700 dollars in there, it is going to be a good investment because we all know that bitcoin is going to be over $10000 by the next year.
And the other 30%, use it to buy ethereum, it is rising up so fast and i am sure that it is going to hit five hundred dollars soon.
