No; prices are not 'soaring rapidly' with Reddcoin. There is still a lot of sell weight. And movement right now is SAT to SAT. Reddcoin has actually been surprisingly stable as compared with a lot of other altcoins (and over the past year price has basically doubled from 3.5 SATs to 7.5 SATs.
Buy support is strong. 100+ BTC at anytime on Poloniex. Also, roadmap and wallet updates, and decentralized updates, and RDD-ID I think will either keep price stable, or slowly drive price up.
I am a big believer in Dogecoin and Reddcoin. I am buying both. I think both are way undervalued. They had fair distribution so the price is a true market price, and they are pretty low market caps considering community involvement.
You could buy in with ETH or ETC or XMR or XRP, but you are basically buying in at a $100MM+ market cap. It takes a lot more to move a $100MM+ market cap to $200MM+ to double your money than it takes for example Dogecoin to move from $25MM market cap to $100MM market cap to quadruple your money.
Look at community involvement, development roadmaps, development team, and fair-distribution before you buy any crypto ..
