Increasing your wealth having only $150 initial funds is hard. It is unfortunate because to gain more, you need more, and with that little money your progress won't be impressive. That is, if you try to multiply your money carefully without risking it. I think somewhat safe route is lend this money with interest.
I agree that $150 of BTC is a very small amount.
I cannot really subscribe to any gambling or game of chance - even though bitcoin could be characterized as such.
At this point, however, if you have been studying BTC, there seems to be a considerable battle going on , and really the BTC price seems quite bottomed out.
I have been accumulating BTC for nearly two years, since the top of the last bubble, so I may NOT be the best person in the world to be following.
Since my overall BTC portfolio is in the red, I have recently devised ways to divide my portfolio into three parts, and then in the near future, I will be able to trade parts of the portfolio because theoretically, that portion of the portfolio will go sufficiently in the black in accordance with my trade parameters.
I am NOT sure if my method will make me rich or cause me to accumulate more BTC and some of them at a lower cost or to trade the ups and downs....but NONETHELESS, I am currently of the opinion that I have devised a plan that will allow me to 1) trade a portion of my BTC 2) mostly HODL BTC in case the price goes up 3) take advantage of likely ongoing BTC price volatility, 4) both continue to accumulate BTC while hedging portions of my BTC portfolio NO matter the direction of BTC short-term price moving (assuming that BTC prices will go up in the long term).
I am NOT much of a gambler, yet I believe that my way forward plan is less boring than a strict buy and HODl plan, even though my current plan retains some buy and HODL features.
