>100 bitcoins. Will I be a millionaire by 2020?
No.
Why not? bitcoin prices are always unpredictable, as we now touched $500 in a short time. so in 2020 may be 100 bitcoin be a millionaire, if the price above $1000 No.
Bitcoin already reached $1000 highs. Remember how that shit-show turned out ?
The fundamentals are not yet there, for Bitcoin to be valued at 1BTC/$10,000USD.
I doubt the price would even go to 10.000. It's just to high if you ask me. At best the price may go to 3000/5000k but there are never guarantees.
For that matter, it's also possible the price will go back to 1 dollar if some very bad news arrive.
So better to be very carefull, it's your money after all
All those different ans huge markets Bitcoin can and will have an influence on will make it possible to see a price of $10k/bitcoin.
Sure this sounds totally crazy right now, but it also sounded crazy when people said Bitcoin will reach the 1k per coin.
Just alone 1% of the actual gold market would push Bitcoin up to 4000+!!!
And now think about stocks, real estates, bonds, derivates, foreign remittances and so on.
Of course this will take and is no guarantee.But the potential is there!!
