It's not enough having an investment plan, knowing the right choice to make for every investment defines the investor better. Take for example jumping on every new coin we find on reputable exchange might not be enough guarantee that coin will do well in the future.
There are many ways to invest and must be smart. First, you need to fully understand what you are investing in, no doubt Bitcoin is the best but Altcoins could be a source of good investment as well if prioritized and watched. Bitcoin is the only stable Crypto I know and when playing with Altcoin it needs to be on short-term basis as many are not decentralized or fully decentralized as claimed.
