Bitcoin is a great system because once you spend your satoshis you need to either work for more, invest into something or buy more as today but there is no one killing your purchasing power by way of fractional reserved and any trick that banks have with the current monetary system. Whales will manipulate the price in the meantime because they can scare you away from buying or selling but once people accept Bitcoin as a medium of exchange that is it, you will have to do something to gain your Bitcoin back so those who save will have wealth and those who spend can't double spend or gain something out of nothing, the fact that our current system gives to a tiny elite something out of nothing is unfair to start and that is why bank, institutions fear bitcoin because they get it, their free launch is about to be taken away by Bitcoin.
