I voted for BTC because its the most trusted one and i got a lot of return from BTC than any other Altcoins.Still i am holding BTC and i know that my profit is sure.Other beneficial and growing coins in my basket contain ETH,NEO,XRP,EOS.ETH i am still in profit and i use XRP as short term trading.NEO,EOS i am just holding for long term and i am sure that these two coins have great potential to grow drastically in coming few years.
