Have you considered the vexPolyCUB to imply more than just the name and it's sphere of approach? I see this to be more or like a life time investment as it calls for. The peripheral view gives one a glue of putting in coins (polyCUB) and locking it, but it shows more to that as has more view.
Your friend 
A look at what investment is all about and what is curtained in it,there are no much 100percent guarantees to them if they aren't much planned out and targeted to hit a spot as at when it's expected to be due as to make use of it, then if that be the case a thorough and a well meaning and looked through investments should be scouted out before making a step to it, but to vexPolyCUB it's much more than that.
The view of Investment on polyCUB down to vexPolyCUB
I strongly believe that much work, thinking and rethinking has been carried out before the lunch of polyCUB talk more of vexPolyCUB, so I give kudos to the officials that facilitated this approach and to bring it to lim light even this present time, making more meaning to leofinance community. polyCUB just a token like others on Hive Blockchain and much more on leofinance community but the difference being that much potentials and portfolios lies behind it much more than other token on the leofinance community as at the moment because of its recent update and most talked about aspect which is the vexPolyCUB.
Run down to this being the purchase of polyCUB,staking it and been called xpolyCUB and then locking the staked polyCUB which is the xpolyCUB to about 2years which is then called vexPolyCUB. A whooping percentage of gain been analysed and put forth at the end of the locking which adds much weight to people that bought the idea and invested much more.
More or like a life Investment
Seeing that a well planned life bargained to have riches and enjoy at it's fullest must have a concrete investment to Carter for it,then a well scouted investment worthy of trust should be looked for. Looking at the vexPolyCUB I termed much more like a life Investment has much to offer in life. Imagine investing much on vexPolyCUB now whereas ones retirement calls in about 2years time as at when the profits and all surrounding will be available, then ones retirement is then full of joy and soundness. Apart from retirement,looking forth at vexPolyCUB as a business terrain is another angle of yield to the investor.
If not vexPolyCUB,then what ..., I believe on this idea
