Stablecoins are a special case of cryptocurrencies which emerged as a response to the high volatility generated in the cryptocurrency market, using a pegging mechanism the stablecoins obtain more stability that could be simulated using artificial neural network (ANN). The objective of this paper is to determine the best activation function between sigmoid, linear or tanh and to forecast a period of 4 days using a basic ANN that could help an investor to determine an entrance or exit point in a stablecoin. As a main result, in all cases the sigmoid activation function is the best option using ANN, although using a basic ANN doesn’t present an accurate forecast in all cases; therefore, it could be used as a supplementary tool that would help the investor to forecast the stablecoin market and improve their portfolio. This was obtained by comparing statistically 50 registers obtained of root-mean-square-error (RMSE).
