bitcoin is so high risking for long time so that if you have estra money safe it will be 0$ or 100000$
I believe it is more likely the bigger one

. The only parameter you need to check is, market saturation, people acceptance, speculative traders, company involvement and government acceptance. It seems bitcoin almost have them all so definitely there is no way for bitcoin but to move upward. Price will definitely go up as the market is being saturated, bitcoin being adopted and more and more speculative traders joining the trend.
