This is my personal opinion, and do not take it as your investment guide. Always do your own research,

Blocknet might be one of the oldest Masternode projects in this space just like Dash, PIVX, Bitsend and else, but it does not mean it has more potential compared to the newly Masternode project. Let's talk about Bitsend, did you see how bad Bitsend is right now? it happened because the project lack of demand and growth, and look at Blocknet.
from demand of view, its total buy orders from various exchanges are 10BTC and its total volume in 24 H just around $3000. That means the demand is very low, and look at their development. Do you see any significant change or development happened with them? I do not see it. From this alone, I can tell you the risk of holding it is higher compared to the others and the return of holding it is lower compared to holding (let's say) ETH. You might lose it all once the final bear appears.

if you are asking me, what to do? then I will say, find something that is fresh and have a good concept. Like Masternode based on SIM Card or anti-sim swap project, because it is going to be lively. Since Verizon has made their move
