new gTLDs are quite difficult to sale if they are not best of the best at the moment..names should be in correct order and have a clear and intuitive meaning, otherwise there will be 0 interest..
.Cheap will work at the moment only with best keywords, like insurance.cheap or flights.cheap..

ifein.space - nice hack, but somebody can register lifeinspace.xyz or lifeinspace.vip or lifeinspace.link, etc..so probability of good resale is limited by these options
given.life..I love .life, it is very good new gTLD..not sure however about value of this particular combo..seems like givenlife.com is pretty well developed though
