Based on the current market conditions, the possibility of XRP crossing five dollars this year is very small. Although the possibility is small, there is nothing impossible in the crypto market.
Highest I feel we might reach is to go test the previous ATH around $3 and that would still be some pretty good one anyway, if we get to see it happen.
For now, I would not want to bank on seeing more than that. However, like you said, even the impossible has happened in this market several times and we cannot simply say there could not be a possibility, but however it is, I want to believe that it is better not to get too greedy expecting the most, when the market generally can quickly take the bad shape and better to always get out when you still can.
If it goes to $5, we will slightly experience a short term correction after hitting the previous ATH and then a continuation, so there will still always be room to get in on little if that becomes a reality.
