nobody is forcing you to do so.
you can trust whatever you want, bitcoin is decentralized and nobody needs to convince others what to choose. you need to come up with it yourself. if you end up finding X better then go with X and if you found Y better then go with Y.
heck you can even go to
https://bitcointalk.org/index.php?board=159.0 and choose whichever you find more "trustable" than bitcoin.
only time and consensus and the price which shows amount of adoption will tell who was right and who wasn't.
