Bitcoin will not rise straight up to 50k. We will see many up and down before Btc reaching high level. One days ago (30 Apr) Bitcoin price again down to 28k. now its looking weak and we can again see some further correction to 26k and then it will be time for whale to push big than previous and 35k might he target in this pump.
A straight rise to 50k would be kinda impossible given the current market conditions. It's currently undergoing a price correction, and it's probable that it will remain in the range of 25k to 35k for some time, possibly two to three months. However, I believe it could reach another level by the end of this year, possibly around the range of 40k to 50k.
Personally I find it quite unlikely that price would be between $25K and $35K for two to three months, mainly as price has already been between $20K and $30K for around for 4/5 months, which is a similar range, as well as consolidated between $27K and $31K for about 5/6 weeks now. So eventually price is likely to break this range in either direction and go some distance as well as not return there for sometime (or ever).
It's also worth remembering that it didn't take long for price to go from $20K to $30K, which is a 50% increase, so going from $30K to say $45K wouldn't necessarily take much longer.
