Invest for bitcoin at that time will be a very risky and unwise step.Also Bitcoin spends a long time from the last time it was giving a golden chance to the people.Untill Now it is not improving at all and get stuck in seven thousand usd though it was twenty thousand once.so that is more better to invest in another currency of market it is cheap in price and almost has the full percentage to get lrofit of it than bitcoin.
So I will say Inveat for bitcoin now will never a be a good idea.
