been holding cloak for a month now almost, no regrets (first coin ive held after day trading since april).
Tips for new investors, buy at market price some but setup buy orders to also catch dumps at lower prices to best alter your weighted average and maximize profit potential. Never underestimate dumpers, as market factors (like mintpal hack) and individuals fudding or selling thanks to short term opportunities always creates some downward pressure.
Plenty of chances to buy in at great prices thanks to volatility of altcoin markets (cant believe i picked up bunch of coins at .00067 last night on bittrex).
