You better buy bitcoin now and sell them at peak near block reward halving time or july of next year. To invest in blockchain requires lots of fund, so if you could get much profit out of that bitcoins than try to invest in blockchain based companies and services if you like.
Quite a nice move if you bought in the $200 ranges. But the thing about bitcoin is that you can't actually predict the top. That feeling when you sold and feel that it won't rise anymore and afterwards, you see that it goes on and on and on makes you feel like an idiot and think of buying again at high prices, only to be caught up by others already selling, so long term hodling is still the best thing to do imo.
