I see a lot of people talking about when to sell; but I think that buying is as important if not more (obviously you buy* low -_-). so do you guys aim to buy the lowest low of the day/week/month/... and do you think that is riskier and/or hard to predict. do you wait for price reversals? do you follow expert advice?? please share your thoughts and your stories (successful or otherwise

)
For me as a trader, I will look for the update of the coin I am going to buy if that coin has active developer and always get update on their platform. I also buy at a very low price if I cannot buy it is okay but I can buy much better. As for now its the middle of hard fork so I need to hold my coins and bitcoins and wait for the updates.
looking for the update of the coins is a good idea to know the info before we buy the coins and sometimes we have a new clue that will help us to determine the price. and if we can buy at lower price then we are lucky and we are only waiting the increase of the price. for bitcoin price, i think we can prepare to buy when we see the price is trying to make correction so we can place the order buy. by placing the order, i think we don't have to missed the good price to buy.
