I would definitely focus on short-term, high-volume low-profit margins of day trading despite having small accretion of income. It is important to note that high-volume trading is important as long as I accumulate profit at the end of the day no matter how low it may be. In-addition, the recent bullish market should be seen as an opportunity to all investors who are hoping to get at least a profit from there investments.
But going with the top5 or even top10 coins is not much risk. Buy whenever you see a dip, sell whenever you feel its time to do so. If you're wrong, simply wait until the next wave.
Higher the risk, higher the reward. Same thing with the top 10 coins in the market being a relatively low risk and reward. Depends if you are well-armed with research and technical analysis, you could try your chances from pump and dump until the next cycle.
