There's no way we will see the gains that we encountered in 2017 unless you're investing in startups, you need to wake up and smell the coffee burning. My guess is that at bitcoins current price, you'd be lucky to double your money.
Yes you are correct and that's why everybody is investing in small caps to get those 100x gains instead of 1.5x gains.
This is why people are suggesting BTC to be represented in mBTC because the price would be smaller at least.
People are $10000 and think it's too expensive for them and buy Ripple or Tron instead.
