My strategy : buy with all you savings which you can afford and HODL. When the bear attacks, buy and the again HODL
Good strategy and l prefer also buying any coin at a low price and hold till price increasing, then sell them. Maybe it is the best strategy, but during this time it is so hard to find any coin which can be profitable in the future. For that reason l prefer top altcoins, l think if you can be enough patient you should collect some top altcoins like ETH. That is why top altcoins are great choice for long term investing, it seems price increasing will take a long time.
I have to say this is not a good move at all! You can do the buy and hold thing, but do not use all of your capital! The rule of most investors I know is that they never invest more than 80% of their capital into a single project. That's too risky. Agree that when it succeed, you earn more profits. However, what if it fails? Allocating capital to various projects is also a skill that traders and investors should learn!
