Never put in more than you can afford too lose. There will always be falls but i personally believe BTC will rise in the long term. People have been asking is it too late all year.What is bitcoin worth now, 500 - 600 pounds, What was it worth this time last year, 10 pounds. Year before, 1 pound. I think you get my point. However we don't truly know what will happen, but there are a lot of people who believe BTC is the future
