My only advice is to read more and explore the vast cryptospace, do not be locked inside the bitcoin box, there are other cryptocurrency out there that is successful and not getting you hands on them is not really a good idea since you are missing out on profit.
Yes to make choices in altccoins is another cool way for profit, the bull run has made the market in green and hodler who have altccoins that they feel were shits but they have appreciated tremendously.
