Since about a year, i told my brother in law (website designer) several times about btc.
I bought my first batch in may 2013, second batch in november 2013, third batch may 15 2014, just sold some fractions of btc to test exchange processing and transfer time.
Last april on a family reunion i asked him if he looked into btc, he said btc was passé already.....
You can lead a horse to water.....
Edit to add: other people i told about btc had no spare money to buy in, new kitchen, just bought an appartment, car etc etc....
I consider myself lucky to be debt free.
I was saving money to buy a BMW X5 but once I had the money I just could not "waste" it all on a car....
Instead I bought a second hand Mercedes E280 and used the surplus money to buy btc. Never ever regretted this.
