Yes it's very true at all,this is a good time to buy or start bitcoin investment. Don't be sad the price of bitcoin down, we should think positively on future bitcoin prices will recover. But what I fear many people say bitcoin prices down there are some countries that ban bitcoin, hopefully it's temporary.
Stick to what you believe and do not fear what other people say. The truth is that people will always talk and if you cannot stand firm on your own decision and the idea of what you are holding being a part of the future, then whatever people say will be of nothing to you.
Everything is always temporary, uptrend, downtrends are all temporary but the fact is, as long as you are holding for long, you really have nothing to worry about.
