Since FSN can be sliced into time slices it can get a little confusing how much FSN you actually have. When you slice a full FSN (by full FSN I mean FSN without any type of TL and that you could send to exchanges or use in liquidity contracts) it will be divided in two parts. One which lasts from current time, until a time you chose to slice it at, if that time is 4 months into the future you will have created some 4 month TL FSN and simultaneously sent the slice off to another wallet (as the slicing happens in a tx). The second part remains in your wallet and is the infinity end of that FSN. The infinity end can also be sent other places, if desired (but, like all TL FSN will not be accepted by exchanges). As long as you have the infinity end of FSN, you can be considered its true owner.
