Then why not invest in the safest bet Ethereum. Currently, it is @ $545, which is almost 62% down from the recent all-time high. And it is surely gonna reach $2k+ in the next bull run. So, you can easily 3-4x your investment.
What this guy said. for such a large sum you should invest in a top 20 coin (for safety) and given the current pricing i would also pick ethereum.
