Its a tough one isnt it. I would recommend staying away from new coins when they first appear on the market unless you get in really quick as almost always the price spikes then crashes. Also I would never (not now anyway lol) but a coin that is massively increasing in value. As when you buy in often it has hit its peak and starts plummeting. Of course this could be my own bad luck. I have done well looking at established coins and assessing their lows and highs and trying to place bids near their lows and selling when they bounce back up.

I will be fascinated to see what advice you get as I am interested too

Someone is bound to say Buy low, sell high! which is true but how do you know at what point to buy!

I think too that there is money to be made if you go in big. When I made some cash of shadowcoin I wished I could have afforded to buy more because I made fifty percent of my stake!
