Very possible to be rich with bitcoin but I think we can be better when we don't keep in the wallet for so long.
The rate is already high, we don't have to get too greedy.
We can covert to local currency and to be careful not to invest in a scam site
Investment have really become very risky nowadays as its very hard to find any legit site to invest our bitcoins as there is a full possibility that those sites will scam you in long run so the best choice would be to keep them safe in wallet or else use some of them in trading.
