Looking at the latest developments and increasing interest towards the XRP, by the end of 2018, the Ripple price is expected to cross the $7 barrier at least.
I think it can really reach that level, everything is possible in this coin but you still be careful because it can drop so hard. A lot of big companies are now using XRP, it can be a reason for the price pump. Trade wisely with XRP so you will not incur loss, $5 this year is easy for this coin and expect correction after that.
