The designation SGD implies a Singapore dollar, Singapore's national payment unit. It cannot be called valuable in the context of the world currency market, so the pairs formed with it are more likely to be exotic and difficult to predict. On the contrary, the English pound is a popular and stable currency with high liquidity. At best, the combination of GBP / SGD can bring some revenue. To assess it most accurately, you can familiarize yourself with the comparative characteristics of the pair with EUR / USD, the most significant pair in the market.
