XSN is a great coin to hold as you can earn passive income whilst doing so. The options are to stake through XSN Cloud for smaller holdings, or you can stake through TPoS, a cold-staking innovation of Stakenet. Your coins remain offline in your wallet whilst a merchant stakes your coins for you (they don't have access to your coins, you remain in full control) and rewards flow straight to your wallet. Imo, very undervalued at the moment given they are currently running Lightning Swaps and innovating in Lightning Network technology, have an upcoming decentralized P2P network, Dapps, their own hardware device etc. One to watch. Masternodes require 15,000 XSN which in the current market is $1500 with average monthly income of 196 XSN (15% annual ROI).
