If you can not research and decide for yourself you should not be buying any of them. You will not get good answers here asking this so do not bother.
Yeah, your right.. In buying altcoins it will need observation first deciding to buy it, Now if ever you are confuse or double minding about it. I think it is not deserve for the buyer to buy it. Because as far as I know if You/We buying the other coins/altcoins you must be real all the time for it.
