I don't know about GRAM and LAW, but I know about Libra, because Libra has a relationship with Facebook, making Libra popular, but I suggest you better not invest in new coin, because the coin doesn't have a real project, so what was promised by the coin has not been proven and I would rather advise you to invest in coin that already have a real project, so I'm sure the coin will definitely increase and my suggestion for a good coin to invest for now is UBT, because I see UBT has a real project and of course the price of UBT hasn't increased very high, so the opportunity for the price of UBT to increase very high will surely occur, but it's just that we have to be patient until the price of UBT increases very high and gives a big profit.
Check Gram and especially LAW. I listed them as I appreciate their tech and solid teams a lot
Why LAW?
