Every time i come across the question i always tell someone to go and see the chart. who knew back in 2010 that btc will be worth 7k in 2018. its never too late to be part of the crypto community. the segment is getting big every single day. more people are getting into this sector thus more money is also getting into the sector. then years from now you would wish you had joined the sector. and come 2018 there are a number of people who will be getting in the sector and they will think they are late but they will be wrong.
