I noticed this phenomenon. Often someone buys up all the proposed tokens with a small amount of trading (for example, look at SMT on hitbtc this night), and after a few days these tokens go up in price very much. Is it worth buying such a token?
It's quite risky but its worth it when its value skyrockets. You just have to pick which token to invest make sure that their technology is promising and theirs a room for the value of the token to skyrocket in the near future or else your investments will go down the drain. Sometimes most of these tokens are just used for pumps and dumps so invest only an amount that you can afford to lose.
I agree with your suggestion. As long as you do a very good research of the coin you want to invest in and you are sure that it is a very good one with good potentials and technology, you can buy when the price is low and then hold because when the market recover, it will rise higher again and then you can sell and make reasonable profit.
