A lot of people here have posted great ideas - but really reading your post, I think you want to be AGGRESSIVE.
Look for undervalued coins that have growing communities and an active team. It will take some research on your part.
Now as far as HOW aggressive will determine how many top coins you bring into your cryptfolio vs how many baby or small coins. I'm a fan of privacy coins as I foresee a huge shift into privacy coin investment once any government actually cracks down on traceable coins and scares the hell out of those public-coin hodlers. But just my hypothesis.
MINT has made me tons of $$. Its project is alive and well compared to a few months ago. An undervalued, well-working PoStake coin that has extremely fast transaction times and tiny tiny tiny fees. It has just gathered investor attention- check them out.
ETH is undervalued as of typing this message.
XVG (a bit biased here) has a rabid following and is awaiting mass adoption. Their new Wraith Protocol is ToR + SA's built into one. Great tech.
DeepOnion is a new currency that might capture a small market share of the privacy coin market. It has a very small market cap as of this writing also, like MINT. A baby coin so do your research.
GVT is also an appealing and solid project - It has seen great growth and also has dropped significantly from the holiday ATHs like many other coins. Very transparent about its team and mission. I think it's a great idea. Connects retail investors with professional traders.
Buying some USDT / LTC ready for trades is always a good idea. Don't forget DOGE.
Also keep an eye on PolyMath. Similar to GVT but more for bringing securities and investments into the cryptospace.
I would advise against coins that have been steadily losing their share of the market caps - older coins that have just been overtaken by newer coins with better features. I won't bash coins on here but keep that in mind.
If this helped you with saving time / doing some research, feel free to give me a +1
Again, I wish you the best of luck, but please, please make sure you do your own due diligence and not solely depend on the advice of others.
You will do great. Welcome to the cryptospace where money grows out of nowhere hehe
