It's main competitors appears to be Tokencard and Blockpay. Tokencard though is a bit different in offering a physical card linked to your ERC20 tokens on Ethereum while Plutus is Bitcoin only. Tokencard doesn't mention Tap and pay either but appears to be more decentralized at first glance. Plutus has about a one year head start.
İ dont know about tokencard but Blockpay is a bithsares munich scam ,there are many articles on steem about it. Also blockscam needs a extra device at every shop,restaurant etc. İt isnt a contactless nfc payment system with a DEX like Plutus.
İ had coins but i could luckily sell at least half the price i bought them at the ico. İ lost BTC and just got the dollar value back because of the btc price increase..... damn scammers..
