bitcoin question

You should really wait if you want to invest atm. BTC has been acting very weirdly for the past 3-4 months. 1BTC was about 16 grand 2 months ago and now it's 6.
Even ethereum has been doing badly, only today the value has dropped by about 1.35%.
Crypto-currency is doing quite badly right now, so you might want to wait up until September or October to actually start investing, as that's when the prices will slowly rise by about ~10-20USD every few days.
