in fact children and teenagers need to take interest in their education and when they complete their education then they can think about using bitcoin for earning money. i thin then bitcoin will have become more stable and reliable.
Bitcoin nature or any Crypto Currency nature is not allowing it to be Stable , Yes reliability can get achieved ( but still in doubt )
Stability is not possible bcoz of its un-natural backup. The more hashpower someone have obviously he can mine more bitcoin and the more someone have means Market of Crypto is in there hand. If they dump big chunk of bitcoin same day market can fall down.
Reliability some how achieved due to opensource , but still under doubt due to attacks which network is facing in everyday life. Its still a code platform so reliability will remain in Question even if it get achieved.
