I say #XRP is #crypto because like you said it uses blockchain technology. Whether it is a good investment depends on your investment strategy. There is no drawback to the fact that it was created for corporations because corporate acceptance of cryptos and their adaption of blockchain technology is what will ultimately stabilize crypto and weed out the useless ones. Having it more widely accepted as payment and by banks gives it more fundamental value. The fact that Google holds 60% of XRP is a non factor. The reason I say that is because there are other cryptos such as #BCH where something like 80% is held by like 3 people and makes it subject to pump and dump. Google may release some XRP as you said to stabilize pricing but it is highly unlikely that they will employ the unethical practice of pump n dump.
I believe there are some solid opportunities day trading ripple using #TA as it still trends in line with #btc #eth #ltc and as we all know, Google is willing to lose money in order to grow a product.
Happy investing!
